I ordered a bunch of stuff last night. Couldn't find the LED driver (or a replacement) at either Mouser or Digikey. Since I'm not in a rush, I didn't worry about that one - Mouser seems to indicate that they're expecting receipt of some right after the first of the year.
For the 5V regulator, I ordered:
Mouser #: 511-L7805ABV
Mfr. #: L7805ABV
Desc.: Linear Regulators - Standard 5.0V 1.0A Positive
- what appears to be the same part with a different operating temperature range (if I remember correctly, -40 to +100C - vs. the original part's 0 - 150C or some such). With the recent LE problem with the 3.3v regulator's temp range, it seems really prudent to replace the original spec'd regulator (which should NEVER need to run over 100C) with one that is rated to go below 0C (of which Mouser has lots in stock).
I'd like to hear if you find the LED driver somewhere else...
Good luck!
