TS431/431A/431B Adjustable Precision Shunt Regulator Sink Current Capability up to 100mA General Description The TS431/431A/431B 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 0.22. 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 convenient to obtain a stable reference from 5.0volt logic supplies, and since The TS431/431A/431B operates as a shunt regulator, it can be used as either a positive or negative stage reference. This series is offered in 3-pin TO-92, SOT-89, SOT-23 and SOP-8 package. Features Precision Reference Voltage TS431 2.495V±2% TS431A 2.495V±1% TS431B 2.495V±0.5% Equivalent Full Range Temp.
