KA431/KA431A/KA431L
Programmable Shunt Regulator
www.fairchildsemi.com
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
• Temperature Compensated for Operation Over Full Rated
Operating Temperature Range

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.
