The 80 µA minimum cathode current means the shunt needs at least that much bias to regulate; below that the output voltage drifts. The 15 mA maximum output current limits direct drive to small loads — above that an external NPN or MOSFET buffer extends the range. ## Temperature range and industrial fit That puts it in scope for outdoor telecom cabinets, factory-floor sensor modules, and under-hood electronics where the ambient sees freeze-thaw cycles but not the full 125°C of automotive under-hood. The SOT-23-3 footprint is a standard three-pin layout shared with the TL431 family, so the board layout is drop-in compatible with the larger TO-92 or SOT-89 siblings — just watch the pin 1 orientation on the reel.","metaTitle":"TLV431IDBZRG4 Adjustable Shunt Reference, ±1.5%, SOT-23-3","metaDescription":"Texas Instruments TLV431IDBZRG4 adjustable shunt voltage reference, 1.24 V min output, ±1.5% tolerance, 15 mA output, SOT-23-3.","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":"±1.5%","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":"15 mA","Current - Supply":"-","Current - Cathode":"80 µA","Base Product Number":"TLV431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~85°C(TA)","Voltage - Output (Max)":"6 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/4de43c4ff3ead6fd17ae3f61f4aa48c4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431IDBZRG4/alternatives.json"},"ai":{"faq":[{"question":"Can TLV431IDBZRG4 replace a standard TL431?","answer":"The TLV431IDBZRG4 is pin-compatible with the TL431 in the same SOT-23-3 footprint, but the reference voltage range differs: the TLV431 adjusts from 1.24 V to 6 V, while the TL431 goes up to 36 V.
