Output is adjustable from 1.24 V up to 6 V via two external resistors, with a maximum cathode current of 15 mA. The shunt topology means it sinks current through an external series resistor; the minimum cathode current of 100 µA must be maintained to keep the reference in regulation. ## Thermal range and package fit The SOT-23-5 package (SC-74A, SOT-753) is a standard surface-mount footprint — no surprises for the pick-and-place line. Listed as Active — no end-of-life or last-time-buy risk.","metaTitle":"TLV431BQDBVRQ1 AEC-Q100 Shunt Reference, ±0.5% Tolerance","metaDescription":"Texas Instruments TLV431BQDBVRQ1 adjustable shunt voltage reference, AEC-Q100 qualified, ±0.5% tolerance, -40°C to 125°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":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Tolerance":"±0.5%","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":"15 mA","Current - Supply":"-","Current - Cathode":"100 µA","Base Product Number":"TLV431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°C(TA)","Voltage - Output (Max)":"6 V","Supplier Device Package":"SOT-23-5","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"1.24V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5115","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ab870328e89d21690c01cf15e0faf994.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TLV431BQDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TLV431BQDBVRQ1 automotive qualified?","answer":"Yes, it is listed under the Automotive, AEC-Q100 series, making it suitable for automotive-grade designs requiring the AEC-Q100 qualification."},{"question":"What is the tolerance of TLV431BQDBVRQ1?","answer":"The reference tolerance is ±0.5%, tighter than the standard 1% grade available in the TLV431 family."},{"question":"Can TLV431BQDBVRQ1 replace TL431?","answer":"The TLV431 is a lower-voltage variant of the TL431 — it operates down to 1.24 V reference vs the TL431's 2.5 V.
