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.
