Description

The TL431/TL431Aare three-terminal adjustable regulator

series with a guaranteed thermal stability over applicable

temperature ranges. The output voltage may be set to any

value between VREF (approximately 2.5 volts) and 36 volts

with two external resistors These devices have a typical

dynamic output impedance of 0.2W Active output circuitry

provides a very sharp turn-on characteristic, making these

devices excel lent replacement for zener diodes in many

applications.
