The 5LP02N is covered by this 42.2 KB PDF, catalogued as a schematic but most likely a component datasheet. Nothing besides the part code is stated in the name; the LP letters in this series appear to denote a P-channel MOSFET and the N suffix a specific package. Look up pin assignment, on-resistance and absolute maximum ratings before testing the device or choosing a substitute. Package outline and marking should be matched to the part on the board, as variants share electrical data but not footprints.
