LM2936
Ultra-Low Quiescent Current LDO Voltage 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
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 40C to +125C
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.

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.
