Hi,
I got this SCPH-70xxx, opened it and noticed that the cr2032 battery leaked and corroded part of the area below, including this regulator IC. According to the service manual it is a MM1579AFBE. Unfortunately some of the pins were snipped and it is unobtainium. Any ideas to replace it without pulling it from a donor board?
