AX431 Series
Adjustable Shunt Regulator
Description
The AX431 series are three-terminal adjustable regulators with guarante-
ed thermal stability over applicable temperature ranges. The output
voltage may be set to any value between V_REF (approximately 2.495 volts)
and 36 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
