The 1.8 MHz to 4 MHz switching range lets you place the fundamental above the AM broadcast band for noise-sensitive automotive loads, or drop to the lower end to improve light-load efficiency. The SOT-583 package measures roughly 2×2 mm — the copper pad area on the PCB sets the thermal resistance, so the layout footprint directly determines how much current you can draw at 125°C ambient without hitting the thermal shutdown. ## Automotive temperature grade and input range The input voltage range of 2.7V to 6V suits 3.3V or 5V rails in automotive ECUs, infotainment, and ADAS sensor power chains. Synchronous rectification eliminates the external Schottky diode, keeping the BOM count low and the efficiency curve flat across load. The fixed 3.3V output means no external feedback divider — one less resistor pair to place and qualify. Texas Instruments lists no PCN or EOL notice for this order code as of the current date.","metaTitle":"TPS6285021HQDRLRQ1 – 3.3V Fixed 2A Buck Regulator, AEC-Q100","metaDescription":"Texas Instruments TPS6285021HQDRLRQ1 is an automotive-grade (AEC-Q100) synchronous step-down regulator delivering 3.3V fixed output at 2A.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR) Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SOT-583","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Base Product Number":"TPS6285021","Output Configuration":"Positive","Frequency - Switching":"1.8MHz ~ 4MHz","Operating Temperature":"-40°C ~ 125°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-583","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7200","priceTiers":[{"qty":1,"price":"$1.72000","currency":"USD"},{"qty":10,"price":"$1.54700","currency":"USD"},{"qty":25,"price":"$1.45960","currency":"USD"},{"qty":100,"price":"$1.24350","currency":"USD"},{"qty":250,"price":"$1.16756","currency":"USD"},{"qty":500,"price":"$1.02162","currency":"USD"},{"qty":1000,"price":"$0.84648","currency":"USD"},{"qty":4000,"price":"$0.78810","currency":"USD"},{"qty":8000,"price":"$0.75891","currency":"USD"},{"qty":12000,"price":"$0.72973","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/7643d68b8c4111119e7d3e0b1a06bd99.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6285021HQDRLRQ1/alternatives.json"},"ai":{"faq":[{"question":"What is the closest functional second-source for TPS6285021HQDRLRQ1?","answer":"The LM53625LQURNLRQ1 is a 2.5A synchronous buck in a similar package, but its switching frequency is fixed at 2.1 MHz and its input range starts at 3.9V — not a pin-compatible drop-in.
