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.
