TS431-Z

Adjustable Precision Shunt Regulator

SOT-23

Pin Definition:

1. Reference

2. Cathode

3. Anode

General Description

TS431 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 to 250mA with a typical dynamic

impedance of 0.2Ω. 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 2.495V reference makes it

convenient to obtain a stable reference from 5.0V logic supplies, and since The TS431 operates as a shunt

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