This makes it a direct drop-in for circuits that need a stable 1.225 V rail — for example, biasing an ADC reference input or setting a comparator threshold. With a ±2% tolerance, the actual output can range from about 1.200 V to 1.250 V at 25°C. For applications that need tighter accuracy, consider the ±0.5% or ±1% variants in the same LM4041 family. ## 12 mA output and 73 µA cathode current — load and quiescent trade-off The shunt reference can sink up to 12 mA of output current, which is enough to bias a typical ADC, op-amp, or small logic load. The cathode current is only 73 µA, so the quiescent draw is low — important for always-on automotive modules or battery-powered designs where every microamp counts. ## SOT-23-3 package — footprint and layout The part comes in a standard SOT-23-3 package (also listed as TO-236-3, SC-59). The three pins are cathode, anode, and no-connect (NC). The small footprint saves board space, but the 0.95 mm pin pitch means careful soldering — reflow profile per the datasheet is recommended.","metaTitle":"LM4041QEEM3X-1.2NO Shunt Voltage Reference, AEC-Q100","metaDescription":"LM4041QEEM3X-1.2NO automotive AEC-Q100 shunt reference, fixed 1.225 V output, ±2% tolerance, -40°C to 125°C, SOT-23-3.","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":"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":"$0.3827","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4041QEEM3X-1.2NO/alternatives.json"},"ai":{"faq":[{"question":"Is LM4041QEEM3X-1.2NO automotive grade?","answer":"Yes, it is listed under the Automotive series and is AEC-Q100 qualified."},{"question":"What is the tolerance of LM4041QEEM3X-1.2NO?","answer":"The initial tolerance is ±2%.
