1.5 A high-side switch with adjustable current limit
The TPS2552DRVT-1: The 100 mOhm typical on-resistance keeps voltage drop under 150 mV at full load, which matters for USB and 5 V rail distribution where the downstream device sees the switch's drop as a loss in input headroom.
Supply range and fault protection
Fault protection includes adjustable current limiting, over-temperature shutdown, and undervoltage lockout — the current limit is set with an external resistor, so the trip threshold can be dialled to match the load's inrush profile.
Orientation mark is on pin 1 corner; the package is symmetric enough that a misalignment on reflow will short the adjacent pins.
