LM2937

500mA LOW DROPOUT

VOLTAGE REGULATOR



DESCRIPTION

LINEAR INTEGRATED CIRCUIT

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.


