H431 Series
ADJUSTABLE SHUNT REGULATOR
Description
The H431 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
