LM2936-3.0

Ultra-Low Quiescent Current 3.0V Regulator

General Description

Features

n Ultra low quiescent current (I_Q≤ 20 µA for I_O= 100 µA)

n Fixed 3.0V, 50 mA output

The LM2936-3.0 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 LM2936-3.0 is ideally suited for automotive and

other battery operated systems. The LM2936-3.0 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 LM2936-3.0 has a 40V maximum operating voltage

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

3% output voltage tolerance over the entire output current,

input voltage, and temperature range. The LM2936-3.0 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.

2% Initial output tolerance

3% Output tolerance over line, load, and temperature

n Dropout voltage typically 200 mV I_O= 50 mA

n Reverse battery protection

n −50V reverse transient protection

n Internal short circuit current limit

n Internal thermal shutdown protection

n 40V operating voltage limit

n 60V operating voltage limit for LM2936HV

n Shutdown pin available with LM2936BM package

Typical Application

20001601

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

Required for stability. Must be rated for 22 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.
