[QUOTE="MODAT7, post: 239430, member: 13649"] You can have lots of processors on the same regulator. It just needs to have enough current to be stable. If a processor (or digital chip in general) produces a lot of rail noise, then it will need isolation and/or a lot of capacitance to filter it (probably throw in some inductors). Main PC CPU's often have a large bank of capacitors around them. The other problem mentioned is ground noise / ground bounce. That's more of a layout design issue, and depending on the chip frequency, can get into magic. They usually need a good star topology that they don't get. Things like audio ADC/DACs are obviously sensistive to noise, so they usually have extra separation... or at least they "should". When doing audio, for example, most USB ports are heavily criticized for being noisy, when it's mostly a ground noise issue from the rest of the computer. That's not the easiest thing to clean up.
