It can source or sink up to 100 mA and operates from the reference voltage up to 36 V. The SOT-23-5 package (SC-74A, SOT-753 footprint) keeps board area small, making it a fit for dense power supplies, bias generators, and comparator threshold circuits. ## Output current and voltage headroom The 100 mA output current rating sets the load-driving ceiling — enough to bias multiple op-amp stages or drive the feedback network in an isolated flyback converter. The 36 V maximum output gives plenty of headroom for 24 V industrial rails or 12 V automotive supplies without needing a cascode stage. The 1 mA minimum cathode current means the reference stays in regulation even at light load, so the design does not need a dummy load resistor. The SOT-23-5 package is a standard footprint; the 0.95 mm pin pitch and 1.6 mm body width fit on two-layer boards without fine-line routing.","metaTitle":"TL431IDBVT Shunt Voltage Reference, 2.495 V, ±2.2%, SOT-23-5","metaDescription":"Texas Instruments TL431IDBVT adjustable shunt voltage reference. 2.495 V min output, 100 mA output, ±2.2% tolerance, -40°C to 85°C, SOT-23-5.","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); Cut Tape (CT)","Tolerance":"±2.2%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"100 mA","Current - Supply":"-","Current - Cathode":"1 mA","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-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.495V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.4150","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2e8567ad04842692d5fb8309c69e90b6.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431IDBVT/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of the TL431IDBVT?","answer":"The TL431IDBVT has a ±2.2% tolerance on the reference voltage.
