General Description
TS1431 series 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 2.5V reference makes it
convenient to obtain a stable reference from 5.0V logic supplies, and since The TS1431 series operates as a shunt
regulator, it can be used as either a positive or negative stage reference.
