The minimum cathode current is 700 µA, which sets the lower bound for the bias resistor in a shunt configuration. Below that, the reference loses regulation. ## Package and footprint for production Supplied in a SOT-23-5 package, also described as SC-74A / SOT-753. The 5-pin SOT-23 footprint is common across many TL431 variants, so the board layout transfers if you switch between commercial and automotive grades.","metaTitle":"TL431AQDBVRQ1 Automotive Shunt Regulator, ±1%, SOT-23-5","metaDescription":"Texas Instruments TL431AQDBVRQ1 adjustable shunt voltage reference, AEC-Q100 qualified, ±1% tolerance, 100 mA output, -40°C to 125°C.","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":"±1%","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":"700 µA","Base Product Number":"TL431","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"-","Operating Temperature":"-40°C~125°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":"$0.4200","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TL431AQDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TL431AQDBVRQ1 automotive qualified?","answer":"Yes, the TL431AQDBVRQ1 is listed under the Automotive, AEC-Q100 series, meaning it has passed the AEC-Q100 stress tests for automotive-grade reliability."},{"question":"What is the tolerance of TL431AQDBVRQ1?","answer":"The TL431AQDBVRQ1 has a ±1% initial tolerance on the 2.495 V reference voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TL431AQDBVRQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TL431AQDBVRQ1 when reusing this data.
