Description

The TL431ILPG, 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 . 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. TL431ILPG Features • Programmable Output Voltage to 36 V• Voltage Reference Tolerance: ±0.4%, Typ @ 25°C (TL431B)• Low Dynamic Output Impedance, 0.22  Typical• Sink Current Capability of 1.0 mA to 100 mA• Equivalent Full−Range Temperature Coefficient of 50 ppm/°C Typical• Temperature Compensated for Operation over Full Rated Operating Temperature Range• Low Output Noise Voltage• Pb−Free Packages are Available
