Description
The KA431S / KA431SA / KA431SL are three-terminal adjustable regulator series with a guaranteed thermal stability over applicable temperature ranges. The output voltage can be set to any value between VREF(approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 Ω. Active output circuitry provides a sharp turn on characteristic, making these devices excellent replacement for Zener diodes in many applications.
