At 3 A output, the power dissipation in the TO-220-7 package requires a heatsink for continuous operation above moderate ambient temperatures — the junction-to-ambient thermal resistance of the bare package is roughly 50°C/W, so a 2 W loss pushes the junction 100°C above ambient.","metaTitle":"Texas Instruments LM2676T-12/NOPB SIMPLE SWITCHER","metaDescription":"Texas Instruments LM2676T-12/NOPB SIMPLE SWITCHER step-down regulator, 3A output, 12V fixed, 8-40V input, TO-220-7, active production.","metaKeywords":null},"attributes":{"series":"SIMPLE SWITCHER®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"SIMPLE SWITCHER®","Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-220-7 Formed Leads","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"260kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"40V","Voltage - Input (Min)":"8V","Supplier Device Package":"TO-220-7","Voltage - Output (Min/Fixed)":"12V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.56","priceTiers":[{"qty":1,"price":"$5.56000","currency":"USD"},{"qty":10,"price":"$4.99500","currency":"USD"},{"qty":25,"price":"$4.72240","currency":"USD"},{"qty":100,"price":"$4.09270","currency":"USD"},{"qty":250,"price":"$3.88280","currency":"USD"},{"qty":500,"price":"$3.48400","currency":"USD"},{"qty":1000,"price":"$2.97000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ad32c7848ea5c4398629a9ea191a4cd3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2676T-12%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"What package does the LM2676T-12/NOPB come in?","answer":"It is supplied in a through-hole TO-220-7 package with formed leads, suitable for socket or solder-in assembly."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM2676T-12-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/LM2676T-12-NOPB when reusing this data.
