Description
The CA723 and CA723C are silicon monolithic integrated cir-
cuits designed for service as voltage regulators at output volt-
ages ranging from 2V to 37V at currents up to 150mA.
Each type includes a temperature-compensated reference
amplifier, an error amplifier, a power series pass transistor, and
a current-limiting circuit. They also provide independently acces-
sible inputs for adjustable current limiting and remote shutdown
and, in addition, feature low standby current drain, low tempera-
ture drift, and high ripple rejection.
The CA723 and CA723C may be used with positive and nega-
tive power supplies in a wide variety of series, shunt, switching,
and floating regulator applications. They can provide regulation
at load currents greater than 150mA and in excess of 10A with
the use of suitable n-p-n or p-n-p external pass transistors.
The CA723 and CA723C are supplied in the 10 lead TO-100
metal can(T suffix), and the 14 lead dual-in-line plastic package
(E suffix), and are direct replacements for industry types LM723,
LM723C in packages with similar terminal arrangements.
