LM723/LM723C

Voltage Regulator

General Description

The LM723/LM723C is a voltage regulator designed prima-

rily 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 fea-

tures extremely low standby current drain, and provision is

made for either linear or foldback current limiting.

The LM723/LM723C is also useful in a wide range of other

applications such as a shunt regulator, a current regulator or

a temperature controller.

The LM723C is identical to the LM723 except that the

LM723C has its performance guaranteed over a 0˚C to

+70˚C temperature range, instead of −55˚C to +125˚C.
