The ±0.5% initial tolerance and 50 ppm/°C temperature coefficient make it a solid choice for precision feedback dividers in switching regulators, ADC reference inputs, or as a stable bias in sensor conditioning circuits. ## 12 mA output and 70 µA cathode current — sizing the series resistor The LM4051 can sink up to 12 mA of output current. The minimum cathode current is 70 µA. The base product number is LM4051, and the 'C' grade indicates the ±0.5% tolerance tier; there are also lower-tolerance 'A' and 'B' grades in the same family if your design needs tighter accuracy. ## SOT-23-3 footprint — layout notes The LM4051CIM3-ADJ is supplied in a SOT-23-3 package, also listed as TO-236-3 / SC-59 / SOT-23-3. The three pins are: cathode, anode, and adjust.","metaTitle":"LM4051CIM3-ADJ Adjustable Shunt Voltage Reference, ±0.5%","metaDescription":"LM4051CIM3-ADJ adjustable shunt reference, 1.212V min output, ±0.5% tolerance, 20µVrms noise, -40°C to 85°C, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Series":"-","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Tolerance":"±0.5%","Output Type":"Adjustable","Part Status":"Not For New Designs","Manufacturer":"Texas Instruments","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":"70 µA","Base Product Number":"LM4051","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C ~ 85°C (TA)","Voltage - Output (Max)":"10 V","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"50ppm/°C","Voltage - Output (Min/Fixed)":"1.212V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.1753","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e499b7cd54f3272232db27a8df268948.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4051CIM3-ADJ/alternatives.json"},"ai":{"faq":[{"question":"What is the footprint of LM4051CIM3-ADJ?","answer":"The LM4051CIM3-ADJ uses a standard SOT-23-3 footprint, also listed as TO-236-3 / SC-59 / SOT-23-3.
