LM2937

500mA LOW DROPOUT

VOLTAGE REGULATOR

DESCRIPTION

The UTC

LM2937

is a positive voltage regulator capable of

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

transistor provides a low dropout voltage characteristic. With a

load current of 500mA 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 operating

temperature range). Special circuitry has been incorporated to

minimize the quiescent current to typically only 10mA with a full

500mA load current when the input to output voltage differential is

greater than 3V.

The UTC

LM2937

requires an output bypass capacitor for

stability. 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 UTC

LM2937

is stable for all ESR below

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

Ideally suited for automotive applications, the UTC

LM2937

will

protect itself and any load circuitry from reverse battery

connections, two-battery jumps and up to +60V/-50V load dump

transients. Familiar regulator features such as short circuit and

thermal shutdown protection are also built in.
