What the 2.5V–6V supply range means for your rail budget
The TPS65053RGET accepts an input voltage from 2.5V to 6V, which covers single-cell Li-ion (3.0V–4.2V), two-cell alkaline, or a regulated 5V USB bus. That 2.5V floor means the PMIC stays alive even as a battery discharges deep into its curve — useful for OMAP-based handhelds where the processor needs a clean shutdown before the cell hits 2.7V.
Industrial temperature grade — not just a mobile part
That matters if the board lives in an outdoor enclosure, a vehicle cabin, or near a motor drive. The 24-VQFN exposed pad helps pull heat out of the package when the ambient climbs.
The base product number TPS65053 is a current catalog line, so replacements or future spins will carry the same footprint.
