The shunt topology means it behaves like a Zener — it sinks current from the supply through a series resistor, and the cathode current must stay above 80 µA to maintain regulation. For a 3.3 V rail feeding a 2.5 V reference, the series resistor drops the difference at the maximum load current of 12 mA. The ±0.5% initial accuracy at 25 °C is the room-temperature spread you see first on the meter. That matters when the reference feeds a 12-bit ADC — the drift eats into the LSB budget. ## SOT-23-3 package and Tape & Reel — board-fit and procurement notes The SOT-23-3 (TO-236-3 / SC-59) footprint is a standard three-lead surface-mount package with 0.95 mm pitch.","metaTitle":"TI LM4041CQDBZTG4 Shunt Voltage Reference","metaDescription":"Texas Instruments LM4041CQDBZTG4 precision shunt reference, adjustable output 1.233V-10V, ±0.5% tolerance, 100ppm/°C, 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":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.5%","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","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~125°C(TA)","Voltage - Output (Max)":"10 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"1.233V"}},"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/LM4041CQDBZTG4/alternatives.json"},"ai":{"faq":[{"question":"What is the tolerance of LM4041CQDBZTG4?","answer":"The initial tolerance is ±0.5% at 25 °C."},{"question":"What is the cathode current for LM4041CQDBZTG4?","answer":"The minimum cathode current required for regulation is 80 µA.
