With less than 15 A quiescent current at a 100-A load, the LM2936 is ideally suited for automotive and other battery operated systems. The LM2936 retains all of the features that are common to low dropout regulators including a low dropout PNP pass device, short circuit protection, reverse battery input protection, and thermal shutdown. The LM2936 has a 40-V maximum operating voltage limit, a -40C to 125C operating temperature range, and 3% output voltage tolerance over the entire output current, input voltage, and temperature range. 7.2 Functional Block Diagram IN OUT Current Limit Thermal Shutdown PNP + Bandgap Reference LM2936 GND 7.3 Feature Description 7.3.1 High Input Operating Voltage Unlike namy other PNP low dropout regulators, the LM2936 remains fully operational with VIN = 40 V, and the LM2936HV remains fully operational with VIN = 60 V . Owing to power dissipation characteristics of the available packages, full output current cannot be ensured for all combinations of ambient temperature and input voltage. While the LM2936HV maintains regulation to 60 V, it will not withstand a short circuit to ground on the output when VIN is above 40 V because of safe operating area limitations in the internal PNP pass device. Above 60V the LM2936 will break down with catastrophic effects on the regulator and possibly the load as well. Do not use this device in a design where the input operating voltage may exceed 40 V, or where transients are likely to exceed 60 V. 7.3.2 Thermal Shutdown (TSD) The TSD circuitry of the LM2936 has been designed to protect the device against temporary thermal overload conditions. The TSD circuitry is not intended to replace proper heat-sinking. Continuously running the LM2936 device at TSD may degrade device reliability as the junction temperature will be exceeding the absolute maximum junction temperature rating. If the LM2936 goes into TSD mode, the output current will be shut off until the junction temperature falls approximately 10C, then the output current will automatically be restored. The LM2936 will continuously cycle in and out of TSD until the condition is corrected. The LM2936 TSD junction temperature is typically 160C. 12 Submit Documentation Feedback Copyright (c) 2000-2014, Texas Instruments Incorporated Product Folder Links: LM2936 LM2936 www.ti.com SNOSC48O - JUNE 2000 - REVISED DECEMBER 2014 Feature Description (continued) 7.3.3 Short-Circuit Current Limit The output current limiting circuitry of the LM2936 has been designed to limit the output current in cases where the load impedance is unusually low. This includes situations where the output may be shorted directly to ground. Continuous operation of the LM2936 at the current limit will typically result in the LM2936 transitioning into TSD mode. 7.3.4 Shutdown (SD) Pin The LM2936BM has a pin for shutting down the regulator output. Applying a Logic Level High (> 2 V) to the SD pin will cause the output to turn off. Leaving the SD pin open, connecting it to Ground, or applying a Logic Level Low (< 0.6 V) will allow the regulator output to turn on. 7.4 Device Functional Modes The LM2936 design does not include any undervoltage lockout (UVLO), or overvoltage shutdown (OVSD) functions. Generally, the output voltage will track the input voltage until the input voltage is greater than VOUT + 1 V. When the input voltage is greater than VOUT + 1 V the LM2936 will be in linear operation, and the output voltage will be regulated; however, the device will be sensitive to any small perturbation of the input voltage. Device dynamic performance is improved when the input voltage is at least 2 V greater than the output voltage.

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 LM2936 ultra-low quiescent current regulator features low dropout voltage and low current in the standby mode. The LM2936 has a 40-V maximum operating voltage limit, a -40C to 125C operating temperature range, -24-V input voltage protection and 3% output voltage tolerance over the entire output current, input voltage, and temperature range This following section presents a simplified discussion of the design process. Also the WEBENCH(R) software may be used to generate complete designs. When generating a design, WEBENCH utilizes iterative design procedure and accesses comprehensive databases of components. Please go to www.ti.com for more details. 8.2 Typical Application Figure 21 shows the typical application circuit for the LM2936. For the LM2936 5-V option, the output capacitor, COUT, must have a capacitance value of at least 10 F with an equivalent series resistance (ESR) of at least 300 m, but no more than 8 . For the LM2936 3.3-V and 3-V options, the output capacitor, COUT, must have a capacitance value of at least 22 F with an ESR of at least 300 m, but no more than 8 . The minimum capacitance value and the ESR requirements apply across the entire expected operating ambient temperature range. IN VIN OUT VOUT GND CIN 100 nF * COUT 10 F ** * CIN is required only if the regulator is located more than 3 inches from the power-supply-filter capacitors. ** Required for stability. COUT must be at least 10 F for the LM2936 5-V option, and at least 22 F for the 3.3-V and 3-V options. Capacitance must be maintained over entire expected operating temperature range, and located as close as possible to the regulator. The ESR, of the COUT capacitor must at least 300 m, but no more than 8 . Figure 21. LM2936 Typical Application 8.2.1 Design Requirements Table 1.

This value may be increased without limit. Larger values of output capacitance will give improved transient response. 8.2.2.1.2 ESR Limits The ESR of the output capacitor will cause loop instability if it is too high, or too low. ESR, of the COUT capacitor must at least 300 m, but no more than 8 . 8.2.2.2 Output Capacitor ESR It is essential that the output capacitor meet the capacitance and ESR requirements, or oscillations can result. The ESR is used with the output capacitance in Ceramic capacitors (MLCC) can be used for COUT only if a series resistor is added to simulate the ESR requirement. The ESR is not optional, it is mandatory. Typically, a 500-m to 1- series resistor is used for this purpose. When using ceramic capacitors, due diligence must be given to initial tolerances, capacitance derating due to applied DC voltage, and capacitance variations due to temperature. Dielectric types X5R and X7R are preferred. 8.2.3 Application Curve Figure 22. LM2936 VOUT vs. VIN 9 Power Supply Recommendations This device is designed to operate from an input supply voltage from at least VOUT + 1 V up to a maximum of 40 V. The input supply should be well regulated and free of spurious noise. To ensure that the LM2936 output voltage is well regulated the input supply should be at least VOUT + 2 V. A capacitor at the IN pin may not be specifically required if the bulk input supply filter capacitors are within three inches of the IN pin, but adding one will not be detrimental to operation. While the LM2936 maintains regulation to VIN = 60 V, it will not withstand a short circuit on the output with VIN above 40 V because of safe operating area limitations in the internal PNP pass device. With VIN above 60 V the LM2936 will break down with catastrophic effects on the regulator and possibly the load as well. Do not use this device in a design where the input operating voltage, including transients, is likely to exceed 60 V.

PCB layout practices that are adequate for typical LDOs may degrade the PSRR, noise, or transient performance of the LM2936. Best performance is achieved by placing CIN and COUT on the same side of the PCB as the LM2936, and as close as is practical to the package. The ground connections for CIN and COUT should be back to the LM2936 ground pin using as wide, and as short, of a copper trace as is practical. Connections using long trace lengths, narrow trace widths, and/or connections through vias should be avoided as these will add parasitic inductances and resistances that will give inferior performance, especially during transient conditions 10.2 Layout Examples 6 3 7 2 8 1 VIN 5 GND CIN 4 VSD COUT GND VOUT Figure 23.

LM2936 TO-252 (NDP) Layout 10.3 Thermal Considerations Due to the power dissipation characteristics of the available packages (RJA), full output current cannot be ensured for all combinations of ambient temperature and input voltage. Exceeding the maximum allowable power dissipation as defined by the final package RJA will cause excessive die junction temperature, and the regulator may go into thermal shutdown. Power dissipation, PD, is calculated from the following formula: PD = ((VIN - VOUT) x IOUT) + (VIN x IGND) 16 (1) Submit Documentation Feedback Copyright (c) 2000-2014, Texas Instruments Incorporated Product Folder Links: LM2936 LM2936 www.ti.com SNOSC48O - JUNE 2000 - REVISED DECEMBER 2014 Thermal Considerations (continued) space VIN IIN = IGND + IOUT VOUT IOUT IN OUT GND CIN IGND LOAD COUT Figure 26. Current Paths for Power Dissipation Calculation Knowing the power dissipation (PD), the thermal resistance of the package (RJA), and the ambient temperature (TA), the junction temperature (TJ) can be estimated using the following formula: TJ = (PD x RJA) + TA (2) Knowing the thermal resistance of the package (RJA), the ambient temperature (TA), and the maximum allowed operating junction temperature (TJ) of 125C, the maximum power dissipation can be estimated using the following formula: PD(MAX) = (125C - TA) / RJA (3) Alternately, solving for the required thermal resistance (RJA): RJA = (125C - TA) / PD(MAX) (4) The maximum allowed PD information from Equation 3 can be used to estimate the maximum allowed load current (IOUT), or the maximum allowed VIN: VIN(MAX) = (PD(MAX) / IOUT) + VOUT IOUT(MAX) = (PD(MAX) / (VIN - VOUT)) (5) (6) As an example, an application requires : VIN = 14 V, VOUT = 5 V, IOUT = 25 mA, and TA = 85C. Find the maximum RJA to keep the junction temperature under 125C. RJA RJA RJA RJA (125C - TA) / PD(MAX) (125C - 85C) / ((14 V - 5 V) x 0.025 A) 40C / 0.225W 177C/W (7) (8) (9) (10) The EIA/JEDEC standard (JESD51-2) provides methodologies to estimate the junction temperature from external measurements (JB references the temperature at the PCB, and JT references the temperature at the top surface of the package) when operating under steady-state power dissipation conditions. These methodologies have been determined to be relatively independent of the copper thermal spreading area that may be attached to the package DAP when compared to the more typical RJA. Refer to Texas Instruments Application Report Semiconductor and IC Package Thermal Metrics (SPRA953), for specifics. On the 8-pin SOIC (D) package, the four ground pins are thermally connected to the backside of the die. Adding approximately 0.04 square inches of 2 oz. copper pad area to these four pins will improve the JEDEC RJA rating from 111.4C/W to approximately 100C/W. If this extra copper area is placed directly beneath the SOIC package there should not be any impact on board density. The LM2936 has an internally set thermal shutdown point of typically 160C. Thermal shutdown is outside the ensured operating temperature range and is intended as a safety feature only. Continuous operation near the thermal shutdown temperature should be avoided as it may have a negative affect on the life of the device.
