It operates as a two-terminal shunt device — no external resistor divider needed, just a single current-limiting resistor to the supply rail. The 70 µA minimum cathode current keeps the reference biased in its regulation region, while the 15 mA maximum output current allows it to supply small loads or bias an ADC reference input directly. The 35 µVrms noise spec over 10 Hz to 10 kHz places this part in the low-noise tier for a shunt reference — relevant for 12- to 14-bit ADC reference paths where the reference noise floor must stay below one LSB. ## SC-70-5 footprint — small, but rework demands care","metaTitle":"LM4040DIM7-2.0/NOPB Shunt Voltage Reference, 2.048 V ±1%","metaDescription":"Texas Instruments LM4040DIM7-2.0/NOPB precision shunt reference, fixed 2.048 V output, ±1% tolerance, 35 µVrms noise, SC-70-5.","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); Cut Tape (CT)","Tolerance":"±1%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","Product Status":"Active","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":"SC-70-5","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.2382","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/db47fc1a31c797b619d88478be755429.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040DIM7-2.0%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM4040DIM7-2.0/NOPB obsolete?","answer":"Yes, Texas Instruments has listed this part as obsolete.
