KA723
Precision Voltage
Regulator
Features
Positive or Negative Supply Operation 0.01% line and load regulation Output voltage adjustable from 2V to 37 V Output current to 150mA without external pass
transistor
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.
