It operates as a two-terminal shunt regulator — the same topology as a Zener diode but with much tighter regulation and lower temperature drift. The 73 µA cathode current lets the reference regulate at very low bias, useful in battery-powered or power-sensitive analog front-ends where every microamp counts. Output current is rated 12 mA, enough to bias a resistor divider or supply a small ADC reference input. The 150 ppm/°C temperature coefficient means the output shifts about 0.18 mV over the full range — acceptable for 8-bit to 10-bit accuracy but marginal for 12-bit systems without calibration. ## Sourcing reality — obsolete part, quoted to order Sourcing is through independent distribution — we locate traceable surplus or new-old-stock inventory and quote against your BOM quantity.","metaTitle":"LM4041DEM3X-1.2 Shunt Voltage Reference, 1.225V Fixed, ±1%","metaDescription":"LM4041DEM3X-1.2 precision shunt reference: 1.225V fixed output, ±1% tolerance, 73 µA cathode current, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"73 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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/26af4fd2ab0c421228a4f1c33eae6ec2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041DEM3X-1.2/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM4041DEM3X-1.2?","answer":"As an obsolete part, the LM4041DEM3X-1.2 is not available through standard authorized distribution.
