LM723/LM723C Voltage Regulator

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.
