Short 28.6 KB PDF filed under schematics with the name 3LP01N, a code that resembles a discrete semiconductor part number with an N suffix. The name says nothing about the device or motherboard it was taken from. A document of this size normally lists ratings, electrical characteristics and pin mapping for one part. It is handy when identifying a small component during diode-mode checks or when looking for an equivalent. Verify the complete marking on the package, because neighbouring suffixes such as M, S or C may differ.
