I have a board I was working on and noticed what seems to be the first issue. I have no voltages on pp3v3_s5. My strategy was to look in the schematics and search for a chip it was the output on. I have gone through the schematics many times and must be missing it. The closest chip I found was u7501 on page 54 of the schematic, but that does not seem to clearly indicate that is the source. I see lots lines with pp3v2_s5 as the prefix. But none with just pp3v3_s5 by its self. Could you help me understand what all of the other versions of pp3v3_s5_**** mean? I am just looking for a basic understanding in general. Also, where exactly is pp3v3_s5 come from?
