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 ℃to +70℃
