Programmable Shunt

Regulator

KA431A, KA431L

Description

The KA431A and KA431L are three−terminal adjustable regulators

with a guaranteed thermal stability over the operating temperature

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.

Features

• Programmable Output Voltage to 36 V

• Low Dynamic Output Impedance: 0.2 W (Typical)

• Sink Current Capability: 1.0 to 100 mA

• Equivalent Full−Range Temperature Coefficient of 50 ppm/°C

(Typical)
