The TPS259470LRPWR: The 5.5 A continuous output rating means it can protect a 5 V rail at 27.5 W or a 12 V rail at 66 W without an external pass transistor.
Package and footprint — 10-VQFN-HR (2x2)
Housed in a 10-VQFN-HR (2x2) package — the fine pitch demands a multi-layer board with a solid thermal via array under the exposed pad to keep junction temperature below the 125°C limit at 5.5 A. Surface-mount assembly with standard reflow profile; the small footprint leaves room for input/output capacitors and a sense resistor on the same side of the board.
