Programmable Shunt
Regulator
KA431A, KA431L
Description
The KA431A and KA431L are three−terminal adjustable regulators
with a guaranteed thermal stability over the operating temperature
www.onsemi.com
range. The output voltage can be set to any value between V
REF
(approximately 2.5 V) and 36 V with two external resistors. These
devices have a typical dynamic output impedance of 0.2 W. Active
output circuitry provides a sharp turn−on characteristic, making these
devices excellent replacements for Zener diodes in many applications.
