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
±3% output voltage tolerance over the entire output current,
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

Typical Application
* 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.
