General Description
The TS431I/431AI/431BI 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 0.22
Ω
. 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 to obtain a stable reference from 5.0volt logic supplies, and since The TS431I/431AI/431BI operates as a
shunt regulator, it can be used as either a positive or negative stage reference.
