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 VREF (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. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacement for zener diodes in many applications.
