 		 #184906 - Babble of marketing people...
Responding to: ???'s previous message

"the "a linear supply is always quiter than a switcher" is disproven. "

Come on, Erik. This is the ridiculous gibberish of marketing people. A switcher is always switching and is always producing a ripple somewhere. It's the intrinsic discontinuous working principle of the switcher that causes the produce of ripple. You can decrease the ripple by additional measures, of course. But the switcher will never produce less ripple than a linear regulator, that doesn't produce any ripple at all. That's absurd...
