Supplied in a SOT-23-3 package (TO-236-3 / SC-59 equivalent), surface-mount. The three-pin footprint is standard across the ATL431 family, so a board layout for the base part number accepts this variant without changes.","metaTitle":"ATL431LIAQDBZRQ1 Automotive Shunt Reference, ±1%, AEC-Q100","metaDescription":"TI ATL431LIAQDBZRQ1 adjustable shunt voltage reference, AEC-Q100 qualified, ±1% tolerance, 80 µA cathode current, SOT-23-3, -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":"TO-236-3, SC-59, SOT-23-3","Product Status":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"80 µA","Base Product Number":"ATL431","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-23-3","Temperature Coefficient":"-","Voltage - Output (Min/Fixed)":"2.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.0000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ddf7d8ba5056e7ea46bc3a27a56b5fbb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/ATL431LIAQDBZRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is ATL431LIAQDBZRQ1 automotive qualified?","answer":"Yes, it is listed under the Automotive, AEC-Q100 series.
