The integrated synchronous rectifier eliminates the external catch diode, reducing BOM count and improving efficiency at light loads — the low-side FET replaces the diode's forward drop with a resistive channel. Switching at 400 kHz keeps the inductor and output capacitor small enough for space-constrained 8-SOIC layouts, while staying below the AM band to simplify conducted-emission filtering. ## Output voltage range and thermal envelope The adjustable output can be set from 0.85 V up to 38 V using a resistor divider — the 0.85 V minimum allows powering low-voltage cores like 1.2 V or 1.8 V logic directly from a 12 V bus. Rated for junction temperatures from -40°C to +150°C, the part suits industrial enclosures and under-hood automotive environments where ambient heat pushes the die above 125°C. The 8-SOIC package with a 3.90 mm body width fits standard SOIC-8 footprints; the exposed pad on the 8-SO variant should be soldered to a copper pour on the PCB to pull heat from the die. ## Active lifecycle and compliance Fully ROHS3 compliant, with no restricted substances above the threshold; the part ships in Tape & Reel or Cut Tape for automated pick-and-place assembly.","metaTitle":"STMicroelectronics L6982NDR Step-Down Regulator, 2A, 8-SOIC","metaDescription":"STMicroelectronics L6982NDR step-down (buck) regulator, 2A output, 3.5-38V input, 400kHz switching, adjustable output down to 0.85V.","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":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"400kHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"38V","Voltage - Input (Min)":"3.5V","Voltage - Output (Max)":"38V","Supplier Device Package":"8-SO","Voltage - Output (Min/Fixed)":"0.85V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.95","priceTiers":[{"qty":1,"price":"$2.95000","currency":"USD"},{"qty":10,"price":"$2.65100","currency":"USD"},{"qty":25,"price":"$2.50600","currency":"USD"},{"qty":100,"price":"$2.17200","currency":"USD"},{"qty":250,"price":"$2.06060","currency":"USD"},{"qty":500,"price":"$1.84896","currency":"USD"},{"qty":1000,"price":"$1.55936","currency":"USD"},{"qty":2500,"price":"$1.48139","currency":"USD"},{"qty":5000,"price":"$1.42570","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/1b091c5f2a3bbd5986f4009b928ba2fd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/L6982NDR/alternatives.json"},"ai":{"faq":[{"question":"What package does the L6982NDR come in?","answer":"The L6982NDR is supplied in an 8-SOIC package (0.154\", 3.90 mm width) with the supplier device package 8-SO.
