LM9036 Ultra-Low Quiescent Current Voltage Regulator
April 2004
LM9036
Ultra-Low Quiescent Current Voltage Regulator
General Description
The LM9036 ultra-low quiescent current regulator features
low dropout voltage and low current in the standby mode.
With less than 25碌A(chǔ) 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 鈭?0藲C to +125藲C
operating temperature range, and
鹵
5% output voltage toler-
ance over the entire output current, input voltage, and tem-
perature range.

Typical Application
20001101
* 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.
