LM2936-3.3

Ultra-Low Quiescent Current 3.3V Regulator

General Description

The LM2936-3.3 ultra-low quiescent current regulator fea-

tures low dropout voltage and low current in the standby

mode. With less than 20 µA quiescent current at a 100 µA

load, the LM2936-3.3 is ideally suited for automotive and

other battery operated systems. The LM2936-3.3 retains all

of the features that are common to low dropout regulators

including a low dropout PNP pass device, short circuit pro-

tection, reverse battery protection, and thermal shutdown.

The LM2936-3.3 has a 40V maximum operating voltage

limit, a −40˚C to +125˚C operating temperature range, and

input voltage, and temperature range. The LM2936-3.3 is

available in a TO-92 package, a SO-8 surface mount pack-

age, as well as SOT-223 and TO-252 surface mount power

packages.

Typical Application

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

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

Connection Diagrams

3% output voltage tolerance over the entire output current,

Required for stability. Must be rated for 22 µF minimum over intended operating temperature range. Effective series resistance (ESR) is critical, see
