It operates as a two-terminal shunt (like a Zener), requiring only a series resistor from the supply to the cathode — no external bypass capacitor needed for stability. Noise is specified at 35 µVrms over a 10 Hz to 10 kHz bandwidth, and the temperature coefficient is 150 ppm/°C — adequate for 8- to 10-bit ADC references and general-purpose biasing in industrial control, data acquisition, and power supply feedback loops. ## Through-hole TO-92-3 — hand-solder friendly, but plan for end-of-life The TO-92-3 through-hole package (TO-226-3) is easy to hand-solder and fits standard prototyping grids. ## Sourcing reality — no factory stock, quoted per RFQ With an obsolete status, the LM4040EIZ-3.0/NOPB is no longer manufactured by TI. It is not held in factory stock.","metaTitle":"LM4040EIZ-3.0/NOPB Shunt Voltage Reference, 3V ±2%, TO-92-3","metaDescription":"Texas Instruments LM4040EIZ-3.0/NOPB precision shunt reference, fixed 3V output, ±2% tolerance, 15 mA output, 70 µA cathode current, TO-92-3 through-hole","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Bulk","Tolerance":"±2%","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-226-3, TO-92-3 (TO-226AA)","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"70 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"35µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"TO-92-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8c40cf163b5cda64fd88ad5c9f25fe6d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040EIZ-3.0%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4040EIZ-3.0-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/LM4040EIZ-3.0-NOPB when reusing this data.
