LM723QML

Voltage Regulator

General Description

The LM723 is a voltage regulator designed primarily for

series regulator applications. By itself, it will supply output

currents up to 150 mA; but external transistors can be added

to provide any desired load current. The circuit features

extremely low standby current drain, and provision is made

for either linear or foldback current limiting.

The LM723 is also useful in a wide range of other applica-

tions such as a shunt regulator, a current regulator or a

temperature controller.
