LM2936,pdf datasheet (Ultra-Lo

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 tolerance
over the entire output current, input voltage, and temperature
range. The LM2936 is available in a TO-92 package,
SO-8 and SOT–23 surface mount packages, and a
TO-252 surface mount power package.
