It sinks up to 100 mA continuous cathode current with a minimum operating current of 700 µA, which sets the bias resistor ceiling in a shunt configuration. The SOT-23-3 package (also listed as TO-236-3 or SC-59) keeps the footprint small for dense PCB layouts. ## SOT-23-3 footprint and Tape & Reel delivery The SOT-23-3 package (3-pin, 0.95 mm pitch typical) is a standard small-signal outline. The Tape & Reel shipping format suits high-volume pick-and-place assembly.","metaTitle":"TL431BIDBZTG4 Shunt Reference, ±0.5% Tolerance, SOT-23-3","metaDescription":"Texas Instruments TL431BIDBZTG4 adjustable shunt voltage reference, ±0.5% tolerance, 100 mA output, SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"700 µA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~85°C(TA)","Voltage - Output (Max)":"36 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431BIDBZTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of TL431BIDBZTG4?","answer":"The TL431BIDBZTG4 has a ±0.5% initial tolerance on the reference voltage.
