A 27.1 KB PDF titled with the part code 5LP01SS, stored in the schematic category but evidently a small datasheet. No further details are in the name; within this family LP seems to indicate the P-channel MOSFET line and SS likely a particular package. Use it to confirm which pin is gate, drain and source, and to read threshold voltage and current limits before measuring or replacing the part. Check the package size against the board pads, since the suffix variants are physically different.
