Description
The AX432 series are three-terminal adjustable regulators with
guaranteed thermal stability over applicable temperature ranges. The
output voltage may be set to any value between V
REF
(approximately 1.24
or 1.25 volts) and 30 volts with two external resistors. These devices have
a typical dynamic output impedance of 0.2鈩? Active output circuitry
provides a very sharp turn-on characteristic, making these devices
excellent replacement for zener diodes in many applications.
