1 / 9 page  TL431 Programmable Precision References FEATURES l Programmable Output Voltage to 36 Volts l Low Dynamic Output Impedance, 0.22 Ω Typical l Sink Current Capability of 1.0 to 100 mA l Equivalent Full-Range Temperature Coefficient of 50 ppm/oC Typical l Temperature Compensated for operation over Full Rated Operating Temperature Range l Low Output Noise Voltage TO-92 The TL431 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 Ω. The characteristics of these references make them Pin: 1. Reference 2. Anode 3. Cathode excellent replacements for zener diodes in many applications such as digital voltmeters, power supplies, and op amp circuitry. The 2.5 volt reference makes it convenient to obtain a stable reference from 5.0 volt logic supplies, and since the TL431 operates as a shunt regulator, it can be used as either a positive or negative voltage reference. PINARRANGEMENT DIP-8 Pin: 1. Cathode 6. Anode 8. Reference Other Pins: NC SOP-8 Pin: 1. Cathode 5. NC 2. Anode 6. Anode 3. Reference 7. Anode 4. NC 8. Reference This SOP-8 is an internally modified SOP-8 Package. Pins 2, 3, 6 and 7 are electrically common to the die attach flag. This internal lead frame modification decreases package thermal resistance and increases power dissipation capability when appropriately mounted on a printed circuit board. This SOP-8 conforms to all external dimensions of the standard SOP-8 package.
