KA431/KA431A/KA431L
Programmable Shunt Regulator
Features
• 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

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 0.2W active
output circuitry provides a very sharp turn on
characteristic, making these devices excellent
replacement for zener diodes in many applications.
