KA431 Programmable Shun Regulator Datasheet

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 VREF

(approximately 2.5 V) and 36 V with two external resistors. These devices have a typical dynamic output impedance of 0.2 . 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  (Typical)

Sink Current Capability: 1.0 to 100 mA

Equivalent Full−Range Temperature Coefficient of 50 ppm/°C (Typical)

Temperature Compensated for Operation Over Full Rated Operating Temperature Range

Low Output Noise Voltage

Fast Turn−on Response
