That footprint is the main event: it lets you put a 1 A rail within a few millimeters of the load without a separate inductor or cap array eating board space. Output is adjustable from 0.6 V up to 5.5 V, covering core and I/O rails for most MCUs and FPGAs. ## Switching frequency and thermal headroom Switching frequency spans 1.8 MHz to 4 MHz, set by a single resistor. At 4 MHz the inductor drops to 0.47 µH — that shrinks the total solution footprint, but the switching losses climb. At 1.8 MHz efficiency peaks, but the inductor is larger. The 150°C junction rating means you can run at the higher frequency near a 105°C ambient without hitting the thermal wall. Compare with the LMR33630APCQRNXRQ1, a 3 A automotive buck in a wettable-flank package. The TPS628501DRLR delivers one-third the current but in a fraction of the board area — the SOT-583 is roughly 4 mm² versus the LMR33630's 9 mm². If your load is under 1 A and board space is the constraint, the TPS628501DRLR wins without a re-spin. For a kitting lead planning a 3–5 year production run, that means no forced redesign mid-cycle.","metaTitle":"TPS628501DRLR – Texas Instruments 1 A Buck Regulator","metaDescription":"Texas Instruments TPS628501DRLR step-down buck regulator, 1 A output, adjustable 0.6–5.5 V, 1.8–4 MHz switching, SOT-583 package.

The difference is the output current rating — the TPS628501DRLR is a 1 A device. If your BOM calls for TPS628500 and the load is under 1 A, the TPS628501DRLR is a direct pin-compatible drop-in. Confirm the output current budget before swapping."},{"question":"What is the footprint of TPS628501DRLR?","answer":"The package is SOT-583, a 6-pin 1.6 mm × 1.6 mm body with 0.50 mm pitch. The supplier device package is also SOT-583. The land pattern is in the datasheet; the small pitch means a 2-layer board can route it, but a ground plane under the exposed pad helps thermal performance."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS628501DRLR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS628501DRLR when reusing this data.
