LM2936-5.0

Ultra-Low Quiescent Current 5V Regulator

General Description

The LM2936 ultra-low quiescent current regulator features

low dropout voltage and low current in the standby mode.

With less than 15 µA quiescent current at a 100 µA load, the

LM2936 is ideally suited for automotive and other battery op-

erated systems. The LM2936 retains all of the features that

are common to low dropout regulators including a low drop-

out PNP pass device, short circuit protection, reverse battery

protection, and thermal shutdown. The LM2936 has a 40V

maximum operating voltage limit, a −40˚C to +125˚C operat-

over the entire output current, input voltage, and tempera-

ture range. The LM2936 is available in a TO-92 package, a

SO-8 surface mount package, and a TO-252 surface mount

power package.

* Required if regulator is located more than 2" from power supply filter capacitor.

** Required for stability. Must be rated for 10 µF minimum over intended operating temperature range. Effective series resistance (ESR) is critical, see

curve. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without bound.
