H431AM/BM/CM
AJDUSTABLE SHUNT REGULATOR
Description
The H431XM series are three-terminal adjustable regulators with guaranteed 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 0.2. 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/C typical * Temperature compensated for operation over * full temperature range * Low output noise voltage * Fast turn on response
