It is a three-terminal device in the SOT-23-3 package, designed to provide a stable voltage reference for ADC references, comparator thresholds, and power-supply monitoring in space-constrained boards. ## Output current and cathode current — the load budget The shunt can sink up to 12 mA of output current. The minimum cathode current is 65 µA — below that the reference drops out of regulation. The LM4041EIM3-1.2 carries a Not Recommended for New Designs (NRND) status. This means Microchip will continue to support existing production for a period, but the part is not intended for new design starts. For ongoing production, the BOM should be reviewed for a drop-in replacement or a design revision before the part moves to end-of-life.","metaTitle":"LM4041EIM3-1.2 Shunt Voltage Reference, 1.225 V, ±2%","metaDescription":"LM4041EIM3-1.2 precision shunt reference, fixed 1.225 V output, ±2% tolerance, 12 mA output, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","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":"Not For New Designs","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"65 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":"SOT-23-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5660","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d2855eaed3a119e1ade8ae46dfbd1dff.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041EIM3-1.2/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4041EIM3-1.2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4041EIM3-1.2 when reusing this data.
