GENERAL DESCRIPTION
The FSP431 is three-terminal adjustable shunt
regulators with specified thermal stability over
applicable automotive, commercial, and military
temperature ranges. The output voltage can be set to
any value between Vref (approximately 2.5 V) and 36 V
with two external resistors. These devices have a
typical output impedance of 0.2Ω . Active output
circuitry provides a very sharp turn-on characteristic,
making these devices excellent replacements for Zener
diodes in many applications, such as onboard
regulation, adjustable power supplies, and switching
power supplies.
