The shunt topology means the device regulates by shunting current through the cathode to ground; the 90 µA minimum cathode current sets the floor for bias current, while the 15 mA maximum output current defines the load it can drive directly. In practice, the series resistor from the supply to the cathode must be sized to deliver at least 90 µA at the minimum supply voltage, and the load current plus the quiescent current must stay under 15 mA. The 150 ppm/°C temperature coefficient means the output drifts 0.9 mV over the full range, which is acceptable for 8-bit to 10-bit accuracy but marginal for 12-bit systems without calibration. Because the part is obsolete, buyers should verify date codes and inspect for counterfeit risk when sourcing from the spot market.","metaTitle":"LM4040DIM3-6.0/NOPB Shunt Voltage Reference, 6V ±1%","metaDescription":"Texas Instruments LM4040DIM3-6.0/NOPB precision shunt reference, fixed 6V output, ±1% tolerance, 80µVrms noise, SOT-23-3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Analog & Data Acquisition"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR)","Tolerance":"±1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"TO-236-3, SC-59, SOT-23-3","Product Status":"Obsolete","Reference Type":"Shunt","Voltage - Input":"-","lifecycle_stage":"eol_hot","Current - Output":"15 mA","Current - Supply":"-","Current - Cathode":"90 µA","Base Product Number":"LM4040","Noise - 0.1Hz to 10Hz":"-","Noise - 10Hz to 10kHz":"80µVrms","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"SOT-23-3","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/05b3d05928edfa6db78fdcac523d9f73.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040DIM3-6.0%2FNOPB/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM4040DIM3-6.0-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/LM4040DIM3-6.0-NOPB when reusing this data.
