AJDUSTABLE SHUNT REGULATOR
Description
The H431XM series are three-terminal adjustable regulators with gu-
aranteed thermal stability over applicable temperature ranges. The
output voltage may be set to any value between VREF(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 replacem-
ent for zener diodes in many applications.
Features
• Programmable output voltage
• Temperature coefficient is 50ppm/°C typical
• Temperature compensated for operation over
• full temperature range
• Low output noise voltage
• Fast turn on response
