As a shunt reference, it requires a series resistor to set the bias current and can sink up to 15 mA of load current while drawing a minimum cathode current of 103 µA to maintain regulation. The noise floor is 180 µVrms (10 Hz to 10 kHz). This means TI is not actively promoting this variant for new projects, though it remains available for existing production runs through the independent distribution channel. No official successor order code has been published for this specific tolerance and voltage grade. For new designs, evaluate the broader LM4040 family — the base product number LM4040 covers multiple voltage options and tolerance grades in the same SOT-23-3 footprint, but no direct pin-compatible replacement with the same ±0.1% tolerance at 10V is listed as an official cross-reference. ## SOT-23-3 footprint and supply chain fit Packaged in a standard SOT-23-3 (TO-236-3 / SC-59 compatible) surface-mount package, the LM4040AIM3-10.0 shares the same three-pin footprint as other LM4040 voltage variants. The cathode is the reference output, the anode connects to ground, and the third pin is the no-connect (NC) — the same pinout across the LM4040 family means a board designed for a 2.5V or 5V LM4040 can accept the 10V variant without layout changes, provided the series resistor is recalculated for the higher output voltage.","metaTitle":"LM4040AIM3-10.0 Shunt Voltage Reference, 10V ±0.1%, SOT-23-3","metaDescription":"Texas Instruments LM4040AIM3-10.0 precision 10V shunt reference, ±0.1% tolerance, 100ppm/°C drift, 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":"±0.1%","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":"15 mA","Current - Supply":"-","Current - Cathode":"103 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"180µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"10V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/db47fc1a31c797b619d88478be755429.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040AIM3-10.0/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy LM4040AIM3-10.0 and check current pricing?","answer":"Submit an RFQ for current availability and pricing — stock levels and lead times are confirmed at quote time.
