® LM723
HIGH PRECISION VOLTAGE REGULATOR
s INPUT VOLTAGE UP TO 40V
s OUTPUT VOLTAGE ADJUSTABLE FROM 2
TO 37V
s POSITIVE OR NEGATIVE SUPPLY
OPERATION
s SERIES, SHUNT, SWITCHING OR
FLOATING OPERATION
s OUTPUT CURRENT TO 150mA WITHOUT
EXTERNAL PASS TRANSISTOR
s ADJUSTABLE CURRENT LIMITING
DESCRIPTION
The LM723 is a monolithic integrated
programmable voltage regulator, assembled in
14-lead dual in-line plastic and SO-14
micropackage. The circuit provides internal
current limiting. When the output current excedes
150mA an external NPN or PNP pass element
may be used. Provisions are made for adjustable
current limiting and remote shut-down.
