The fixed 12 V output at 3 A continuous is the headline load rating — size the inductor and output capacitor for that current, not the 52 kHz switching frequency. The TO-220-5 package with through-hole mounting is a reflow-oven exception: it goes through wave solder or hand-solder, not the paste reflow profile. MSL is not a concern for a leaded power package, but the tab (pin 4, substrate) needs a thermal pad or heatsink — the junction-to-case thermal path is the limiting factor for sustained 3 A at high ambient. This is the lead-free / NOPB suffix version of the original LM2576T-12. Pin-compatible, same switching frequency, same inductor selection. If your BOM already calls out the older LM2576T-12, this is a drop-in replacement that keeps you RoHS-compliant without a board respin.","metaTitle":"LM2576T-12/NOPB SIMPLE SWITCHER Buck, 3A, 52kHz, TO-220-5","metaDescription":"Texas Instruments LM2576T-12/NOPB SIMPLE SWITCHER step-down regulator, fixed 12V output, 3A, 52kHz, TO-220-5, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"SIMPLE SWITCHER®","Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Through Hole","Package / Case":"TO-220-5","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Base Product Number":"LM2576","Output Configuration":"Positive","Frequency - Switching":"52kHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"40V","Voltage - Input (Min)":"4V","Voltage - Output (Max)":"-","Supplier Device Package":"TO-220-5","Voltage - Output (Min/Fixed)":"12V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.6900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/74e216c81e85fc39d2b33ae4761c412c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM2576T-12%2FNOPB/alternatives.json"},"ai":{"faq":[{"question":"Is LM2576T-12/NOPB a direct replacement for LM2576T-12?","answer":"Yes — the LM2576T-12/NOPB is the lead-free (RoHS-compliant) version of the original LM2576T-12.
