Electrical specifications do not apply when operating the device outside of its rated operating conditions. If Military/Aerospace-specified devices are required, contact the Texas Instruments Sales Office/Distributors for availability and specifications. The maximum allowable power dissipation is a function of the maximum junction temperature, TJ(MAX), the junction-to-ambient thermal resistance, RJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated using P(MAX) = ( (TJ(MAX) - TA) / RJA). The value of RJA for the SOT-23 package is 175.7C/W. Exceeding the maximum allowable power dissipation will cause excessive die temperature, and the regulator will go into thermal shutdown. If used in a dual-supply system where the regulator load is returned to a negative supply, the LP2980-N output must be diode-clamped to ground. The output PNP structure contains a diode between the IN and OUT pins that is normally reverse-biased. Reversing the polarity from VIN to VOUT turns on this diode (see Reverse Current Path). 6.2 ESD Ratings VALUE V(ESD) (1) Electrostatic discharge Human-body model (HBM), per ANSI/ESDA/JEDEC JS-001 (1) All pins except 3 and 4 2000 Pins 3 and 4 1000 UNIT V JEDEC document JEP155 states that 500-V HBM allows safe manufacturing with a standard ESD control process. 6.3 Recommended Operating Conditions over operating free-air temperature range (unless otherwise noted) Operating junction temperature Input supply voltage Shutdown input voltage MIN MAX UNIT -40 125 C 2.1 16 0 VIN V 6.4 Thermal Information LP2980-N THERMAL METRIC (1) DBV UNIT 5 PINS RJA Junction-to-ambient thermal resistance, High K (2) RJC(top) Junction-to-case (top) thermal resistance RJB Junction-to-board thermal resistance JT Junction-to-top characterization parameter 2.8 C/W JB Junction-to-board characterization parameter 30.3 C/W (1) (2) 175.7 C/W 78 C/W 30.8 C/W For more information about traditional and new thermal metrics, see Semiconductor and IC Package Thermal Metrics.

Available in output voltages from 2.5 V to 5 V, the device has an initial output voltage tolerance of 0.5% for the A grade (1% for the non-A version). Using an optimized vertically integrated PNP (VIP) process, the LP2980-N contains these features to facilitate battery-powered designs: * Fixed 5-V, 4.7-V, 3.3-V, 3-V, and 2.5-V output versions * Low-dropout voltage, typical dropout of 120 mV at 50-mA load current and 7 mV at 1-mA load * Low ground current, typically 370 A at 50-mA load and 80 A at 1-mA load * A sleep mode feature is available, allowing the regulator to consume less than 1 A typically when the ON/OFF pin is pulled to less than 0.18 V. * Overtemperature protection and overcurrent protection circuitry is designed to safeguard the device during unexpected conditions. 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 Multiple Voltage Options To meet the different application requirements, the LP2980-N provides multiple fixed output options from 2.5 V to 5 V. 7.3.2 High-Accuracy Output Voltage With special careful design to minimize all contributions to the output voltage error, the LP2980-N distinguishes itself as a very high-accuracy output voltage micropower LDO. This includes a tight initial tolerance (0.5% typical), extremely good line regulation (0.007%/V typical), and a very low output voltage temperature coefficient, making the part an ideal low-power voltage reference. 7.3.3 Ultra-Low-Dropout Voltage Generally speaking, the dropout voltage often refers to the voltage difference between the input and output voltage (VDO = VIN - VOUT), where the main current pass-FET is fully on in the ohmic region of operation and is characterized by the classic RDS(ON) of the FET. VDO indirectly specifies a minimum input voltage above the nominal programmed output voltage at which the output voltage is expected to remain within its accuracy boundary.

This function is designed for the application which needs a sleep mode to effectively enhance battery life cycle. 7.3.6 Short-Circuit Protection (Current Limit) The internal current-limit circuit is used to protect the LDO against high-load current faults or shorting events. The LDO is not designed to operate in a steady-state current limit. During a current-limit event, the LDO sources constant current. Therefore, the output voltage falls when load impedance decreases. If a current limit occurs and the resulting output voltage is low, excessive power may be dissipated across the LDO resulting in a thermal shutdown of the output. A foldback feature limits the short-circuit current to protect the regulator from damage under all load conditions. If OUT is forced below 0 V before EN goes high and the load current required exceeds the foldback current limit, the device may not start up correctly. 7.3.7 Thermal Protection The LP2980-N contains a thermal shutdown protection circuit to turn off the output current when excessive heat is dissipated in the LDO. The thermal time-constant of the semiconductor die is fairly short, and thus the output cycles on and off at a high rate when thermal shutdown is reached until the power dissipation is reduced. The internal protection circuitry of the LM2980-N is designed to protect against thermal overload conditions. The circuitry is not intended to replace proper heat sinking. Continuously running the device into thermal shutdown degrades its reliability. 7.4 Device Functional Modes 7.4.1 Operation with VOUT(TARGET) + 1 V VIN < 16 V The device operates if the input voltage is equal to, or exceeds, VOUT(TARGET) + 0.6 V. At input voltages below the minimum VIN requirement, the device does not operate correctly and output voltage may not reach target value. 7.4.2 Operation With ON/OFF Control If the voltage on the ON/OFF pin is less than 0.18 V, the device is disabled, and the shutdown current does not exceed 1 A. Raising ON/OFF above 1.6 V initiates the start-up sequence of the device. 14 Submit Documentation Feedback Copyright (c) 2000-2016, Texas Instruments Incorporated Product Folder Links: LP2980-N LP2980-N www.ti.com SNOS733P - APRIL 2000 - REVISED SEPTEMBER 2016 8 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 8.1 Application Information The LP2980-N is a linear voltage regulator operating from 2.1 V to 16 V on the input and regulates voltages between 2.5 V to 5 V with 0.5% accuracy and 50-mA maximum output current. Efficiency is defined by the ratio of output voltage to input voltage because the LP2980-N is a linear voltage regulator. To achieve high efficiency, the dropout voltage (VIN - VOUT) must be as small as possible, thus requiring a very-low-dropout LDO. Successfully implementing an LDO in an application depends on the application requirements. If the requirements are simply input voltage and output voltage, compliance specifications (such as internal power dissipation or stability) must be verified to ensure a solid design. If timing, startup, noise, power supply rejection ratio (PSRR), or any other transient specification is required, then the design becomes more challenging. This section discusses the implementation and behavior of the LP2980-N LDO. 8.2 Typical Application *ON/OFF input must be actively terminated. Tie to IN if this function is not to be used. **Minimum output capacitance is 1 F to ensure stability over full load current range. More capacitance provides superior dynamic performance and additional stability margin (see Output Capacitor Recommendation). ***Do not make connections to this pin.

The efficiency of the LP2980-N in this configuration is VOUT / VIN = 66.7%. To achieve the smallest form factor, the SOT-23 package is selected. Input and output capacitors are selected in accordance with the Output Capacitor Recommendation section. With an efficiency of 66.7% and a 50-mA maximum load, the internal power dissipation is 85 mW, which corresponds to a 14.9C junction temperature rise for the SOT-23 package. With an 85C maximum ambient temperature, the junction temperature is at 99.9C. 8.2.2.1 Output Capacitor Recommendation Like any low-dropout regulator, the LP2980-N requires an output capacitor to maintain regulator loop stability. This capacitor must be selected to meet the requirements of minimum capacitance and equivalent series resistance (ESR) range. It is not difficult to find capacitors which meet the criteria of the LP2980-N, as the acceptable capacitance and ESR ranges are wider than for most other LDOs. In general, the capacitor value must be at least 1 F (over the actual ambient operating temperature), and the ESR must be within the range indicated in Figure 31, Figure 32, and Figure 33. It should be noted that, although a maximum ESR is shown in these figures, it is very unlikely to find a capacitor with an ESR that high. 8.2.2.1.1 Tantalum Capacitors Surface-mountable solid tantalum capacitors offer a good combination of small physical size for the capacitance value, and an ESR in the range needed by the LP2980-N. The results of testing the LP2980-N stability with surface-mount solid tantalum capacitors show good stability with values of at least 1 F. The value can be increased to 2.2 F (or more) for even better performance, including transient response and noise. Small value tantalum capacitors that have been verified as suitable for use with the LP2980-N are shown in Table 1. Capacitance values can be increased without limit. 8.2.2.1.2 Aluminum Electrolytic Capacitors Although probably not a good choice for a production design, because of relatively large physical size, an aluminum electrolytic capacitor can be used in the design prototype for an LP2980-N regulator. A value of at least 1 F should be used, and the ESR must meet the conditions of Figure 31, Figure 32, and Figure 33. If the operating temperature drops below 0C, the regulator may not remain stable, as the ESR of the aluminum electrolytic capacitor will increase and may exceed the limits indicated in Figure 31, Figure 32, and Figure 33.

However, they sometimes have ESR values lower than the minimum required by the LP2980-N, and relatively large capacitance change with temperature. The manufacturer's data sheet for the capacitor should be consulted before selecting a value. Test results of LP2980-N stability using multilayer ceramic capacitors show that a minimum value of 2.2 F is usually needed for the 5-V regulator. For the lower output voltages, or for better performance, a higher value should be used, such as 4.7 F.

During normal operation (where the input voltage is higher than the output) this diode is reverse biased (see Figure 34). VIN VOUT PNP GND Figure 34. LP2980-N Reverse Current Path However, if the input voltage is more than a VBE below the output voltage, this diode will turn on and current will flow into the regulator output. In such cases, a parasitic SCR can latch which will allow a high current to flow into the VIN pin and out the ground pin, which can damage the part. The internal diode can also be turned on if the input voltage is abruptly stepped down to a voltage which is a VBE below the output voltage. In any application where the output voltage may be higher than the input voltage, an external Schottky diode must be connected from VIN to VOUT (cathode on VIN, anode on VOUT, see Figure 35), to limit the reverse voltage across the LP2980-N to 0.3 V (see Absolute Maximum Ratings). 18 Submit Documentation Feedback Copyright (c) 2000-2016, Texas Instruments Incorporated Product Folder Links: LP2980-N LP2980-N www.ti.com SNOS733P - APRIL 2000 - REVISED SEPTEMBER 2016 SCHOTTKY DIODE VIN VOUT PNP GND Figure 35. Adding External Schottky Diode Protection 8.2.2.3 ON/OFF Input Operation The LP2980-N is shut off by pulling the ON/OFF input low, and turned on by driving the input high. If this feature is not to be used, the ON/OFF input must be tied to IN to keep the regulator on at all times (the ON/OFF input must not be left floating). To ensure proper operation, the signal source used to drive the ON/OFF input must be able to swing above and below the specified turn-on and turn-off voltage thresholds which ensure an ON or OFF state (see Electrical Characteristics). The ON/OFF signal may come from either a totem-pole output, or an open-collector output with a pull-up resistor to the LP2980-N input voltage or another logic supply. The high-level voltage may exceed the LP2980-N input voltage, but must remain within the absolute maximum ratings for the ON/OFF pin. It is also important that the turn-on and turn-off voltage signals applied to the ON/OFF input have a slew rate that is greater than 40 mV/s. NOTE The regulator shutdown function will not operate correctly if a slow-moving signal is used to drive the ON/OFF input. 8.2.2.4 Increasing Output Current The LP2980-N can be used to control higher-current regulators, by adding an external PNP pass transistor. With the PNP transistors shown in Figure 36, the output current can be as high as 400 mA, as long as the input voltage is held within the Safe Operation Boundary Curves shown below in Figure 37. To ensure regulation, the minimum input voltage of this regulator is 6 V. This headroom is the sum of the VBE of the external transistor and the dropout voltage of the LP2980-N.

If the shutdown function is not to be used, tie the ON/OFF pin directly to the IN pin. Note B: Recommended devices (other PNP transistors can be used if the current gain and voltage ratings are similar). Note C: Capacitor is required for regulator stability. Minimum size is shown, and may be increased without limit. Note D: Increasing the output capacitance improves transient response and increases phase margin. Note E: Maximum safe input voltage and load current are limited by power dissipation in the PNP pass transistor and the maximum ambient temperature for the specific application. If a TO-92 transistor such as the MPS2907A is used, the thermal resistance from junction-to-ambient is 180C/W in still air. Assuming a maximum allowable junction temperature of 150C for the MPS2907A device, the following curves show the maximum VIN and IL values that may be safely used for several ambient temperatures. Figure 37. Safe Operation Boundary Curves for Figure 36 With limited input voltage range, the LP2980-N can control a 3.3-V, 3-A regulator with the use of a high currentgain external PNP pass transistor as shown in Figure 38. If the regulator is to be loaded with the full 3 A, heat sinking will be required on the pass transistor to keep it within its rated temperature range. See Figure 39. For best load regulation at the high load current, the LP2980-N output voltage connection should be made as close to the load as possible. 20 Submit Documentation Feedback Copyright (c) 2000-2016, Texas Instruments Incorporated Product Folder Links: LP2980-N LP2980-N www.ti.com SNOS733P - APRIL 2000 - REVISED SEPTEMBER 2016 Although this regulator can handle a much higher load current than can the LP2980-N alone, it can be shut down in the same manner as the LP2980-N. When the ON/OFF control is brought low, the converter will be in shutdown, and will draw less than 1 A from the source. Figure 38. 5 V to 3.3 V at 3-A Converter NOTES: Note A: Drive this input with a logic signal (see ON/OFF Input Operation). If the shutdown function is not to be used, tie the ON/OFF pin directly to the IN pin. Note B: Capacitor is required for regulator stability. Minimum size is shown, and may be increased without limit. Note C: Increasing the output capacitance improves transient response and increases phase margin. Note D: A heatsink may be required for this transistor. The maximum allowable value for thermal resistance of the heatsink is dependent on ambient temperature and load current (see curves in Figure 39). Once the value is obtained from the graph, a heatsink must be selected which has a thermal resistance equal to or lower than this value. If the value is above 60C/W, no heatsink is required. For these curves, a maximum junction temperature of 150C is assumed for the pass transistor. The case-toheatsink attachment thermal resistance is assumed to be 1.5C/W. All calculations are for 5.5-V input voltage (which is worst-case for power dissipation). Figure 39.

The input voltage range provides adequate headroom for the device to have a regulated output. This input supply must be well regulated. If the input supply is noisy, additional input capacitors with low ESR can help improve the output noise performance. 10 Layout 10.1 Layout Guidelines For best overall performance, place all circuit components on the same side of the circuit board and as near as practical to the respective LDO pin connections. Place ground return connections to the input and output capacitors, and to the LDO ground pin as close as possible to each other, connected by a wide, component-side, copper surface. The use of vias and long traces to create LDO circuit connections is strongly discouraged and negatively affects system performance. This grounding and layout scheme minimizes inductive parasitics, and thereby reduces load-current transients, minimizes noise, and increases circuit stability. A ground reference plane is also recommended and is either embedded in the PCB itself or located on the bottom side of the PCB opposite the components. This reference plane serves to assure accuracy of the output voltage, shield noise, and behaves similar to a thermal plane to spread (or sink) heat from the LDO device. In most applications, this ground plane is necessary to meet thermal requirements. 10.2 Layout Example VIN VOUT Input Capacitor IN GND OUT Output Capacitor Ground ON/OFF ON/OFF NC Figure 41.
