The minimum cathode current is 70 µA, which sets the lower bound for the series resistor calculation. Maximum output current is 12 mA, so the total current through the device plus any external load must stay under that ceiling to maintain regulation. ## SOT-23-3 footprint and supply posture The three-pin layout — cathode, anode, and no-connect — matches the industry-standard shunt reference pinout used across the LM4041 family.","metaTitle":"LM4041QEIM3-1.2/NO Shunt Reference, AEC-Q100, 1.225V Fixed","metaDescription":"TI LM4041QEIM3-1.2/NO automotive AEC-Q100 shunt voltage reference, 1.225V fixed output ±2%, 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":"±2%","Output Type":"Fixed","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":"12 mA","Current - Supply":"-","Current - Cathode":"70 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.3827","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041QEIM3-1.2%2FNO/alternatives.json"},"ai":{"faq":[{"question":"Is LM4041QEIM3-1.2/NO automotive qualified?","answer":"Yes, it carries Automotive, AEC-Q100 qualification, making it suitable for production in automotive-grade assemblies that require PPAP-level device traceability."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4041QEIM3-1.2-NO","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4041QEIM3-1.2-NO when reusing this data.
