1431A General Description

The TS1431/1431A/1431B 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 nvenient to obtain a stable reference from 5.0volt logic supplies, and since The TS1431/1431A/1431B operates as a shunt egulator, it can be used as either a positive or negative stage reference.

This series is offered in 3-pin TO-92 and SOT-23 package.
