Data Sheet
CA723, CA723C
April 1999
File Number 788.4
Voltage Regulators Adjustable from 2V to
37V at Output Currents Up to 150mA
without External Pass Transistors
The CA723 and CA723C are silicon monolithic integrated
circuits designed for service as voltage regulators at output
voltages 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 accessible inputs for adjustable current
limiting and remote shutdown and, in addition, feature low
standby current drain, low temperature drift, and high ripple
rejection.
The CA723 and CA723C may be used with positive and
negative 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 NPN or PNP
external pass transistors.
