LM2936

Ultra-Low Quiescent Current LDO Voltage Regulator

General Description

Features

n Ultra low quiescent current (I_Q≤ 15 µA for I_O= 100 µA)

n Fixed 3.0V, 3.3V or 5.0V with 50 mA output

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

operated systems. The LM2936 retains all of the features

that are common to low dropout regulators including a low

dropout 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

operating temperature range, and 3% output voltage toler-

ance over the entire output current, input voltage, and tem-

perature range. The LM2936 is available in a TO-92 pack-

age, SO-8 and SOT–23 surface mount packages, and a

TO-252 surface mount power package.

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

00975901

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

** Required for stability. See Electrical Characteristics for required values. Must be rated 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.
