Sizing the 2.5V rail for a 300mA load
The TPS62205DBVR is a fixed 2.5V output step-down converter rated for 300mA continuous output — sized for powering a 2.5V logic rail, sensor supply, or MCU I/O bank on a board that already has a 2.5V to 6V input bus available. The integrated synchronous rectifier eliminates the external Schottky diode, which keeps the BOM count low and the efficiency curve flat across the load range — expect mid-80s to low-90s percent efficiency from light to full load.
Active production and compliance standing
RoHS3 compliant, with no exemptions that would block EU or California market entry. The SOT-23-5 package is lead-free compatible and reflow-ready per JEDEC J-STD-020.
Board-fit and thermal reality
The SC-74A / SOT-753 package is the same 5-lead SOT-23 footprint used across TI's low-power DC-DC family — the PCB land pattern is standard and shared with parts like the TPS62200 series, so a layout swap between fixed-voltage variants needs only a BOM change, not a board spin.
