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 operat-

ing temperature range). Special circuitry has been incorpo-

rated to minimize the quiescent current to typically only

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

put 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 ca-

pacitor remains a critical design parameter, but the LM2937

includes special compensation circuitry that relaxes ESR re-

quirements. The LM2937 is stable for all ESR below 3 . 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 con-
