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.

Features

150 mA output current without external pass transistor

Output currents in excess of 10A possible by adding

external transistors

Input voltage 40V max

Output voltage adjustable from 2V to 37V

Can be used as either a linear or a switching regulator
