INPUT VOLTAGE UP TO 40V OUTPUT VOLTAGE ADJUSTABLE FROM 2 TO 37V POSITIVE OR NEGATIVE SUPPLY OPERATION SERIES, SHUNT, SWITCHING OR FLOATING OPERATION OUTPUT CURRENT TO 150mA WITHOUT EXTERNAL PASS TRANSISTOR ADJUSTABLE CURRENT LIMITING Plastic DIP-14 SO-14
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.
