TS431/431A/431B
Adjustable Precision Shunt
Regulator
Sink Current Capability up to 100mA
General Description
The TS431/431A/431B integrated circuits are three-terminal programmable shunt
regulator diodes.
These monolithic IC
voltage references operate as a low temperature coefficient zener which is programmable from Vref to 36 volts with two
external resistors.
These devices exhibit a wide operating current range of 1.
0 to 100mA with a typical dynamic
impedance of 0.
22Ω.
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.
The 2.
5volt reference makes it convenient ...
