LM2936Q

Ultra-Low Quiescent Current LDO Voltage Regulator

General Description

Features

The LM2936Q 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

LM2936Q is ideally suited for automotive and other battery

operated systems. The LM2936Q 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 LM2936Q 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 LM2936Q is available in a SO-8

package, SOT-223 surface mount package and TO-252 sur-

face mount package.

AEC-Q100 Grade 1 Qualified (-40°C to 125°C)

±2% Initial output tolerance

■

±3% Output tolerance over line, load, and temperature

Dropout voltage typically 200 mV @ I_O= 50 mA

Reverse battery protection

−50V reverse transient protection

Internal short circuit current limit

Internal thermal shutdown protection

40V operating voltage limit

60V operating voltage limit for LM2936HV

Shutdown pin available with the LM2936BM package

Typical Application

30131901

* 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 resis-

tance (ESR) is critical, see curve. Locate capacitor as close as possible to the regulator output and ground pins. Capacitance may be increased without

bound.
