Description
The ET431 is a 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. The 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. The ET431 is characterized for operation from -0 âto +70â
