Description

The KA723 are monolithic integrated Circuit voltage regu-

lators featuring high ripple rejection, excellent output and

load regulation, excellent temperature stability, and low

standby current. The KA723 are also useful in a wide range

of other applications such as a shunt regulator, a current reg-

ulator or a temperature controller.
