Existing production lines that already qualify this reference can still source it through independent distribution, but the window for last-time-buy planning is open now. ## 10 V fixed output, ±1 % — the tolerance that matters This is a fixed 10 V shunt reference, not an adjustable type. The 150 ppm/°C temperature coefficient means the output drifts about 1.5 mV over a 100°C swing — fine for 8- to 10-bit systems, marginal for 12-bit designs without calibration. ## 15 mA output, 110 µA cathode — biasing the shunt The shunt reference needs a bias resistor from the supply to the cathode to set the operating current. The 15 mA maximum output current is the load it can sink while maintaining regulation; the 110 µA minimum cathode current is the floor below which the reference drops out of regulation. A typical design biases it at 1 mA to cover both the load and the cathode minimum with margin. ## SOT-23-3 — footprint and fit Three-pin SOT-23-3 (also listed as TO-236-3 / SC-59). Surface-mount only. The pinout is standard for the LM4040 family: cathode, anode, and no-connect.","metaTitle":"LM4040DIM3-10.0 Shunt Voltage Reference, 10V ±1%, SOT-23-3","metaDescription":"LM4040DIM3-10.0 precision shunt reference: 10V output, ±1% tolerance, 15 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":"±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":"110 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":"150ppm/°C","Voltage - Output (Min/Fixed)":"10V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8c40cf163b5cda64fd88ad5c9f25fe6d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040DIM3-10.0/alternatives.json"},"ai":{"faq":[{"question":"Is the LM4040DIM3-10.0 obsolete or NRND?","answer":"It is not fully discontinued but is on the path to end-of-life.
