It is designed for applications requiring a stable voltage reference — ADC reference, comparator threshold, or precision bias — in a tiny SC-70-5 footprint. No official replacement or successor is listed on the TI lifecycle record. ## SC-70-5 footprint — board-space constraint The SC-70-5 (SOT-353) package measures approximately 2.0mm x 2.1mm with 0.65mm pin pitch. This is the smallest footprint for a precision shunt reference — the part was likely chosen to fit a tight layout. Any replacement must match this land pattern. ## 15 mA output current — load budget check The LM4040CIM7-2.0/NOPB can source up to 15 mA and requires a minimum cathode current of 65 µA to maintain regulation. The shunt topology means the total current drawn from the supply is the load current plus the cathode current — budget the series resistor accordingly.","metaTitle":"LM4040CIM7-2.0/NOPB Shunt Voltage Reference, 2.048V, ±0.5%","metaDescription":"Texas Instruments LM4040CIM7-2.0/NOPB precision shunt reference, 2.048V fixed output, ±0.5% tolerance, 35µVrms noise, -40°C to 85°C.","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":"±0.5%","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":"65 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":"100ppm/°C","Voltage - Output (Min/Fixed)":"2.048V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.5000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/db47fc1a31c797b619d88478be755429.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM4040CIM7-2.0%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM4040CIM7-2.0/NOPB?","answer":"Any substitute must match the 2.048V fixed output, ±0.5% tolerance, and SC-70-5 footprint.
