General Description

The KA431S, KA431SA, and KA431SL are 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 excellent replacement for zener diodes in many applications.
