The FA432/S/F integrated circuits are three-terminal
programmable shunt regulator diodes.
These monolithic IC voltage reference operate as a low
temperature coefficient zener which is programmable from
Vref to 16 volts with two external resistors.

The characteristics of these references make them excellent
replacements for zener diodes in many applications
such as digital voltmeters, power supplies, and op amp circuitry.
