FAN431/FAN431A/FAN431L
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 FAN431/FAN431A/FAN431L are three terminal
output adjustable regulators with thermal stability over
operating temperature range. The output voltage can be
set 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 circuit provides a sharp turn-on characteristic,
making these devices excellent replacement for Zener
Diodes in many applications
