Description

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 0.2Ω. Active output

circuitry provides a very sharp turn on characteristic, making

these devices excellent replacement for zener diodes in many

applications.
