Description

The KA431 / KA431A / KA431L are three-terminal

adjustable regulators with a guaranteed thermal stability

over the operating temperature range. The output volt-

mately 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 replace-

ments for Zener diodes in many applications.
