Sorry for my ignorance, as I'm not that familiar with this model, nor
do I have the schematics. I went on Panasonic's parts site and found
the following IC's, each coming up as being a voltage regulator:

AN78M05
AN78L12
AN7809

I didn't see anythign with the prefix that you mentioned. Given how
cheap the parts are, I may just order all three and replace 'em...
