General Description

TS2431 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 V_REFto 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 TS2431 series operates as a shunt

regulator, it can be used as either a positive or negative stage reference.
