Product Description

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 0.22Ω.
• 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 2.5 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.
