Description
The KA723 are monolithic integrated circuit voltage
regulators 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
regulator or a temperature controller.
