KA431/KA431A/KA431L

Programmable Shunt Regulator

Features

Description

• Programmable Output Voltage to 36 Volts

• Low Dynamic Output Impedance 0.20 Typical

• Sink Current Capability of 1.0 to 100mA

• Equivalent Full-Range Temperature Coefficient of

50ppm/°C Typical

• Temperature Compensated for Operation Over Full Rated

Operating Temperature Range

• Low Output Noise Voltage

The KA431/KA431A/KA431L are three-terminal adjustable

regulator series with a guaranteed thermal stability over

applicable temperature ranges. The output voltage may be

set to any value between VREF (approximately 2.5 volts)

and 36 volts with two external resistors These devices have a

typical dynamic output impedance of 0.2W Active output

circuitry provides a very sharp turn on characteristic,

making these devices excellent replacement for zener diodes

in many applications.

• Fast Turn-on Response
