The cathode current must stay between 75 µA and 12 mA. ## Noise performance for precision measurement That is low enough for 12-bit ADC references without additional filtering in most industrial signal chains. If the application uses a 10 V output, the noise scales with the output voltage — the 20 µVrms figure is at the bandgap level; expect proportionally higher noise at the programmed output. A 0.1 µF bypass cap at the cathode pin helps suppress high-frequency noise coupled from the supply. ## SOT-23-3 package and board integration The part comes in a three-lead SOT-23-3 (TO-236-3, SC-59) package. The small footprint suits dense mixed-signal boards.","metaTitle":"LM4051CEM3X-ADJ/NOPB Adjustable Shunt Voltage Reference","metaDescription":"Texas Instruments LM4051CEM3X-ADJ/NOPB adjustable shunt voltage reference, 1.212V to 10V output, ±0.5% tolerance, 50ppm/°C drift, SOT-23-3, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±0.5%","Output Type":"Adjustable","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":"75 µA","Base Product Number":"LM4051","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"20µVrms","Operating Temperature":"-40°C~125°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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e499b7cd54f3272232db27a8df268948.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4051CEM3X-ADJ%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Can LM4051CEM3X-ADJ/NOPB be used as a voltage reference for an ADC?","answer":"Yes.

For 12-bit or higher, the drift and noise (20 µVrms) may require a system calibration step or a lower-drift reference."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4051CEM3X-ADJ-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM4051CEM3X-ADJ-NOPB when reusing this data.
