It operates as a two-terminal shunt regulator, meaning it sinks current from the supply through an external resistor — no load capacitor needed, and the output voltage stays stable across the full cathode current range of 50 µA to 12 mA. The SOT-23-3 package makes it a drop-in fit for tight layouts where a reference sits next to an ADC or comparator input. Output noise is specified at 60 µVrms over a 10 Hz to 10 kHz bandwidth. For a 12-bit ADC with a 2.5 V reference, that noise contribution is under 0.1 LSB — clean enough for most industrial sensor interfaces. If your design needs better than 0.5% total accuracy across temperature, this part holds the line without external trimming.","metaTitle":"STMicroelectronics LM4041AELT-1.2 Shunt Voltage Reference","metaDescription":"STMicroelectronics LM4041AELT-1.2 precision shunt voltage reference, fixed 1.225 V output, ±0.1% tolerance, 60 µVrms noise, SOT-23-3 package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"STMicroelectronics","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":"Active","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"12 mA","Current - Supply":"-","Current - Cathode":"50 µA","Base Product Number":"LM4041","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"60µVrms","Operating Temperature":"-40°C~125°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"100ppm/°C","Voltage - Output (Min/Fixed)":"1.225V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.4600","stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/06ccf6ae1f4c6fea187fcb5187905d18.pdf","sourceUrl":null},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/LM4041AELT-1.2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/LM4041AELT-1.2 when reusing this data.
