LP4950C-5V, LP4951C www.ti.com SNVS208C - SEPTEMBER 2002 - REVISED APRIL 2013 LP4950C-5V and LP4951C Adjustable Micropower Voltage Regulators Check for Samples: LP4950C-5V, LP4951C FEATURES DESCRIPTION * * * * * * * * The LP4950C and LP4951C are micropower voltage regulators with very low quiescent current (75A typ.) and very low dropout voltage (typ. 40mV at light loads and 380mV at 100mA). They are ideally suited for use in battery-powered systems. Furthermore, the quiescent current of the LP4950C/LP4951C increases only slightly in dropout, prolonging battery life. 1 2 High Accuracy 5V Specified 100mA Output Extremely Low Quiescent Current Low Dropout Voltage Extremely Tight Load and Line Regulation Very Low Temperature Coefficient Use as Regulator or Reference Needs Only 1F for Stability Current and Thermal Limiting . LP4951C VERSIONS ONLY * * * Error Flag Warns of Output Dropout Logic-controlled Electronic Shutdown Output Pogrammable From 1.24 to 29V The LP4950C in the popular 3-pin TO-92 package is pin compatible with older 5V regulators. The 8-lead LP4951C is available in a plastic surface mount package and offers additional system functions. One such feature is an error flag output which warns of a low output voltage, often due to falling batteries on the input. It may be used for a power-on reset. A second feature is the logic-compatible shutdown input which enables the regulator to be switched on and off. Also, the part may be pin-strapped for a 5V output or programmed from 1.24V to 29V with an external pair of resistors. Careful design of the LP4950C/LP4951C has minimized all contributions to the error budget. This includes a tight initial tolerance (.5% typ.), extremely good load and line regulation (.05% typ.) and a very low output voltage temperature coefficient, making the part useful as a low-power voltage reference.

Thermal Response Figure 35. APPLICATION HINTS EXTERNAL CAPACITORS A 1.0F (or greater) capacitor is required between the output and ground for stability at output voltages of 5V or more. At lower output voltages, more capacitance is required. Without this capacitor the part will oscillate. Most types of tantalum or aluminum electrolytics work fine here; even film types work but are not recommended for reasons of cost. Many aluminum electrolytics have electrolytes that freeze at about -30C, so solid tantalums are recommended for operation below -25C. The important parameters of the capacitor are an ESR of about 5 or less and a resonant frequency above 500 kHz. The value of this capacitor may be increased without limit. At lower values of output current, less output capacitance is required for stability. The capacitor can be reduced to 0.33 F for currents below 10 mA or 0.1 F for currents below 1 mA. Using the 8-pin version at voltages below 5V runs the error amplifier at lower gains so that more output capacitance is needed. For the worst-case situation of a 100 mA load at 1.23V output (Output shorted to Feedback) a 3.3 F (or greater) capacitor should be used. Unlike many other regulators, the LP4950C will remain stable and in regulation with no load in addition to the internal voltage divider. This is especially important in CMOS RAM keep-alive applications. When setting the output voltage of the LP4951C version with external resistors, a minimum load of 1A is recommended. A 0.1F capacitor should be placed from the LP4950C/LP4951C input to ground if there is more than 10 inches of wire between the input and the AC filter capacitor or if a battery is used as the input. Stray capacitance to the LP4951C Feedback terminal (pin 7) can cause instability. This may especially be a problem when using high value external resistors to set the output voltage. Adding a 100pF capacitor between Output and Feedback and increasing the output capacitor to at least 3.3F will fix this problem. ERROR DETECTION COMPARATOR OUTPUT The comparator produces a logic low output whenever the LP4951C output falls out of regulation by more than approximately 5%. This figure is the comparator's built-in offset of about 60 mV divided by the 1.235 reference voltage. (See to the block diagram in the front of the datasheet.) This trip level remains "5% below normal" regardless of the programmed output voltage of the 4951C. For example, the error flag trip level is typically 4.75V for a 5V output or 11.4V for a 12V output. The out of regulation condition may be due either to low input voltage, current limiting, or thermal limiting. Figure 36 below gives a timing diagram depicting the ERROR signal and the regulated output voltage as the LP4951C input is ramped up and down. The ERROR signal becomes valid (low) at about 1.3V input. It goes high at about 5V input (the input voltage at which VOUT = 4.75V). Since the LP4951C's dropout voltage is loaddependent (see curve in typical performance characteristics), the input voltage trip point (about 5V) will vary with the load current. The output voltage trip point (approx. 4.75V) does not vary with load.

This resistor may be returned to the output or some other supply voltage depending on system requirements. In determining a value for this resistor, note that while the output is rated to sink 400A, this sink current adds to battery drain in a low battery condition. Suggested values range from 100k to 1 M. The resistor is not required if this output is unused. *When VIN 1.3V, the error flag pin becomes a high impedance, and the error flag voltage rises to its pull-up voltage. Using VOUT as the pull-up voltage (see Figure 37), rather than an external 5V source, will keep the error flag voltage under 1.2V (typ.) in this condition. The user may wish to divide down the error flag voltage using equal-value resistors (10 k suggested), to ensure a low-level logic signal during any fault condition, while still allowing a valid high logic level during normal operation. Figure 36. ERROR Output Timing PROGRAMMING THE OUTPUT VOLTAGE (LP4951C) The LP4951C may be pin-strapped for 5V using its internal voltage divider by tying the pin 1 (output) to pin 2 (sense) pins together, and also tying the pin 7 (feedback) and pin 6 (VTAP) pins together. Alternatively, it may be programmed for any output voltage between its 1.235V reference and its 30V maximum rating. As seen in Figure 37, an external pair of resistors is required. The complete equation for the output voltage is (1) where VREF is the nominal 1.235 reference voltage and IFB is the feedback pin bias current, nominally -20 nA. The minimum recommended load current of 1A forces an upper limit of 1.2 M on the value of R2, if the regulator must work with no load (a condition often found in CMOS in standby). IFB will produce a 2% typical error in VOUT which may be eliminated at room temperature by trimming R1. For better accuracy, choosing R2 = 100k reduces this error to 0.17% while increasing the resistor program current to 12A. Since the LP4951C typically draws 60A at no load with Pin 2 open-circuited, this is a small price to pay. 12 Submit Documentation Feedback Copyright (c) 2002-2013, Texas Instruments Incorporated Product Folder Links: LP4950C-5V LP4951C LP4950C-5V, LP4951C www.ti.com SNVS208C - SEPTEMBER 2002 - REVISED APRIL 2013 *See Application Hints . . **Drive with TTL-high to shut down.

Adjustable Regulator (LP4951C) REDUCING OUTPUT NOISE In reference applications it may be advantageous to reduce the AC noise present at the output. One method is to reduce the regulator bandwidth by increasing the size of the output capacitor. This is the only way noise can be reduced on the 3 lead LP4950C but is relatively inefficient, as increasing the capacitor from 1F to 220F only decreases the noise from 430V to 160V rms for a 100kHz bandwidth at 5V output. Noise can be reduced fourfold by a bypass capacitor across R1, since it reduces the high frequency gain from 4 to unity. Pick (2) or about 0.01F. When doing this, the output capacitor must be increased to 3.3F to maintain stability. These changes reduce the output noise from 430V to 100V rms for a 100kHz bandwidth at 5V output. With the bypass capacitor added, noise no longer scales with output voltage so that improvements are more dramatic at higher output voltages.
