FEATURES

DESCRIPTION

The LM9036 ultra-low quiescent current regulator

2

•

features low dropout voltage and low current in the

standby mode. With less than 25µA Ground Pin

•

Fixed 5V, 3.3V, 50mA Output

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

•

Output Tolerance ±5% Over Line, Load, and

for automotive and other battery operated systems.

The LM9036 retains all of the features that are

Temperature

common to low dropout regulators including a low

reverse battery protection, and thermal shutdown.

•

−45V Reverse Transient Protection

The LM9036 has a 40V maximum operating voltage

limit, a

Typical Application

* Required if regulator is located more than 2

″ from power supply filter capacitor.

** Required for stability. Must be rated over intended operating temperature range. Effective series resistance (ESR)

is critical, see Electrical Characteristics. Locate capacitor as close as possible to the regulator output and ground

pins. Capacitance may be increased without bound.
