SOT-23 Pin Definition: 1. Reference 2. Cathode 3. Anode TS431-Z Adjustable Precision Shunt Regulator 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 VREF to 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.
