When using DC-DC power supply for a PIC-based project, what is considered acceptable (or good, or excellent) ripple voltage? I am using National's Webench to create a DC-DC converter and can get the ripple to a simulated 13mV with components that I can get at DK/Mouser. I'm curious how good this is. I assume that the answer will vary/depend on whether I'm using the A/D module, which I am.
