It delivers up to 15 mA output current with a cathode current of 70 µA, making it a low-power choice for biasing ADCs, DACs, or comparator thresholds in battery-operated or space-constrained designs. The ±2% tolerance is a standard-precision grade — adequate for general-purpose regulation and reference duties, but not for high-accuracy instrumentation where tighter grades (0.1% or 0.05%) are specified. The LM4040EIM7-2.5/NOPB is marked as obsolete by Texas Instruments. For a BOM requiring a 2.5 V shunt reference in SC-70-5, consider the LM4040 family's other tolerance and temperature grades — the LM4040CIM7-2.5 (0.5%) or LM4040AIM7-2.5 (0.1%) may be active alternatives, though their lifecycle status should be confirmed separately. The SC-70-5 package (also known as SOT-353) is a 5-lead surface-mount footprint with 0.65 mm pitch.","metaTitle":"LM4040EIM7-2.5/NOPB Shunt Reference, 2.5 V, ±2%","metaDescription":"Texas Instruments LM4040EIM7-2.5/NOPB shunt voltage reference, fixed 2.5 V output, ±2% tolerance, SC-70-5 package, obsolete.","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":"±2%","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"5-TSSOP, SC-70-5, SOT-353","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":"SC-70-5","Temperature Coefficient":"150ppm/°C","Voltage - Output (Min/Fixed)":"2.5V"}},"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/LM4040EIM7-2.5%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for LM4040EIM7-2.5/NOPB?","answer":"No official direct replacement is listed.
