LM2937

500 mA Low Dropout Regulator

General Description

The LM2937 is a positive voltage regulator capable of sup-

plying up to 500 mA of load current. The use of a PNP power

transistor provides a low dropout voltage characteristic. With

a load current of 500 mA the minimum input to output voltage

differential required for the output to remain in regulation is

typically 0.5V (1V guaranteed maximum over the full oper-

ating temperature range). Special circuitry has been incor-

porated to minimize the quiescent current to typically only

10 mA with a full 500 mA load current when the input to

output voltage differential is greater than 3V.

The LM2937 requires an output bypass capacitor for stabil-

ity. As with most low dropout regulators, the ESR of this

capacitor remains a critical design parameter, but the

LM2937 includes special compensation circuitry that relaxes

ESR requirements. The LM2937 is stable for all ESR below

3Ω. This allows the use of low ESR chip capacitors.

Ideally suited for automotive applications, the LM2937 will

protect itself and any load circuitry from reverse battery
