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 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 replacement for
zener diodes in many applications.
