DESCRIPTION

The LM9036 ultra-low quiescent current regulator

features low dropout voltage and low current in the

standby mode. With less than 25μA Ground Pin

current at a 0.1mA load, the LM9036 is ideally suited

for automotive and other battery operated systems.

The LM9036 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 LM9036 has a 40V maximum operating voltage

limit, a −40°C to +125°C operating temperature

range, and ±5% output voltage tolerance over the

entire output current, input voltage, and temperature

range.
