Page No. : 1/7
AX432 Series
Adjustable Shunt Regulator
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 0.2Ω. Active output circuitry
provides a very sharp turn-on characteristic, making these devices
excellent replacement for zener diodes in many applications.
Features
• Programmable output voltage
• Temperature coefficient is 50ppm/^oC typical
• Temperature compensated for operation over full temperature range
• Low output noise voltage
• Fast turn on response
