Product Overview
TL431A: Voltage Reference, Programmable Precision, Shunt Regulator
For complete documentation, see the data sheet
Product Description
The TL431, A, B 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 V with two external resistors. These devices
exhibit a wide operating current range of 1.0 mA to 100 mA with a typical dynamic impedance of 0.22 <font face=Symbol>W</font>.
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 2.5 V reference makes it convenient to obtain a stable reference from 5.0 V
logic supplies, and since the TL431, A, B operates as a shunt regulator, it can be used as either a positive or negative voltage
reference.
