Hi,
Have always used a traditional linear psu and 5v regulator on my Pic micro projects, but for a new one considering using one of the many smps units commonly available on ebay that power laptops etc.
Have seen a dual output one at 2A 5v and 2A 12v to drive a HDD etc.
Would seem ideal for my Pic project but just a bit sceptical, should I be using any extra filtering or protection on the 5v rail before connecting to the Pic.
