Operating temperature range is -30°C to 85°C, so it's suited for commercial and some industrial environments, but not for under-hood automotive or extended outdoor exposure without derating. ## Active lifecycle — no LTB pressure The LM2771SD/NOPB is listed as Active on TI's product status. That means no end-of-life notice, no last-time-buy clock running. If you're sourcing it through independent distribution, we can quote sealed reels with consistent date-codes — no mixed-date auction lots.","metaTitle":"LM2771SD/NOPB Charge Pump Step-Down, 1.5V Fixed Output","metaDescription":"TI LM2771SD/NOPB charge pump step-down regulator, fixed 1.5V output at 250mA, 2.7V–5.5V input, 1.1MHz switching, 10-WSON package, active status.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Charge Pump","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"250mA","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"1.1MHz","Operating Temperature":"-30°C ~ 85°C (TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.7V","Supplier Device Package":"10-WSON (3x3)","Voltage - Output (Min/Fixed)":"1.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.85","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$1.85000","currency":"USD"},{"qty":10,"price":"$1.65800","currency":"USD"},{"qty":25,"price":"$1.57360","currency":"USD"},{"qty":100,"price":"$1.29290","currency":"USD"},{"qty":250,"price":"$1.20848","currency":"USD"},{"qty":500,"price":"$1.06798","currency":"USD"},{"qty":1000,"price":"$0.84314","currency":"USD"},{"qty":2000,"price":"$0.79541","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ba04119d8a0e4fa87dfaac0d0946dd22.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is a direct replacement or equivalent for LM2771SD/NOPB?","answer":"There is no pin-compatible direct replacement listed. The LM2750LD-ADJ/NOPB is a charge-pump part but it's a step-up (boost) with adjustable output, not a step-down fixed 1.5V. For a step-down charge pump at 1.5V, the LM2771SD/NOPB is the specific part. If you need a higher current or adjustable output, consider a buck converter like the LMS3655 or LM53625, but those are different topologies and packages."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2771SD-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/LM2771SD-NOPB when reusing this data.
