The minimum cathode current is 80 µA, so the bias resistor from the supply rail must be sized to deliver at least that much current at the lowest supply voltage. In a battery-powered design, that 80 µA floor sets the quiescent overhead of the reference branch.","metaTitle":"LM4041C12IDCKRE4 Shunt Voltage Reference, 1.225 V Fixed","metaDescription":"Texas Instruments LM4041C12IDCKRE4 precision shunt reference, fixed 1.225 V output, ±0.5% tolerance, 12 mA output, SC-70-5 package.","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":"±0.5%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"80 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SC-70-5","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/97120b7526b8b1f1915487ff781cf597.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041C12IDCKRE4/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of the LM4041C12IDCKRE4?","answer":"Initial tolerance is ±0.5%."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4041C12IDCKRE4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4041C12IDCKRE4 when reusing this data.
