LM723/LM723C Voltage Regulator
General Description
The LM723/LM723Cisa voltage regulatordesigned primar-
ilyfor series regulator applications.By itself,itwill supply
output currentsupto150 mA;but external transistorscan addedto provideany desired load current. The circuit
features extremelylow standby current drain,and provision madefor either linearor foldback current limiting.
The LM723/LM723Cis also usefulina wide rangeof other
applications suchas ashunt regulator,a current regulatoror temperature controller.
The LM723Cis identicaltothe LM723 except thatthe
LM723C hasits performance guaranteed overa 0§Cto
a70§C temperature range, insteadof b55§Cto a125§C.
Features 150mA output current without external pass transistor Output currentsin excessof 10A possibleby adding
external transistors Input voltage 40V max Output voltage adjustable from2Vto 37V Canbe usedas eithera linearora switching regulator
