LM2936-5.0
Ultra-Low Quiescent Current 5V Regulator
General Description
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 op-
erated systems. The LM2936 retains all of the features that
are common to low dropout regulators including a low drop-
out 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 operat-
ing temperature range, and
over the entire output current, input voltage, and tempera-
ture range. The LM2936 is available in a TO-92 package, a
SO-8 surface mount package, and a TO-252 surface mount
power package.
Typical Application
* Required if regulator is located more than 2" from power supply filter capacitor.
