1 / 14 page TL431/TL432 ADJUSTABLE PRECISION SHUNT REGULATOR TL431/432 Document number: DS35050 Rev. 2 - 2 1 of 14 www.diodes.com September 2010 © Diodes Incorporated Description The TL431 and TL432 are three terminal adjustable shunt regulators offering excellent temperature stability and output current handling capability up to 100mA. The output voltage may be set to any chosen voltage between 2.5 and 36 volts by selection of two external divider resistors. The devices can be used as a replacement for zener diodes in many applications requiring an improvement in zener performance. Diodes’ TL431 has the same electrical specifications as the industry standard ‘431 and is available in 2 grades with initial tolerances of 1% and 0.5% for the A and B grades respectively. Features • Temperature range -40 to 125ºC • Reference Voltage Tolerance at 25°C • TL431A: 2.495V ± 1.0%. • TL431B: 2.495V ± 0.5% • Low Output Noise • 0.2Ω Typical Output Impedance • Sink Current Capability: 1mA to 100mA • Adjustable Output Voltage: V REF to 36V • SOT23 and SOT25: Available in “Green” Molding Compound (No Br, Sb) and Lead Free Finish/ RoHS Compliant (Note 1) Applications • Opto-Coupler Linearisers • Shunt Regulators • Improved Zener • Variable Reference Pin Assignments TL431 ANODE 1 2 CATHODE 3REF 4REF 5ANODE NC 1 CATHODE 3 NC 2 (Top View ) SOT23 SOT25 (Top View) TL432 (Top View) ANODE 1 2 CATHODE 3 REF SOT23 Notes: 1.
