AJDUSTABLE SHUNT REGULATOR
Description
The H431 series are three-terminal adjustable regulators with guara-
nteed thermal stability over applicable temperature ranges. The out-
put voltage may be set to any value between VREF (approximately
2.495 volts) and 36 volts with two external resistors. These devices
TO-92
have a typical dynamic output impedance of 0.2Ω. Active output circ-
uitry 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/°C typical
• Temperature compensated for operation over
• full temperature range
• Low output noise voltage
• Fast turn on response
