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.
