#184901 - a myth debunked ?
this article show that a switcher gives less VCC noise than a linear regulator.

YES, I know that you may be able to find a noiser switcher, and, maybe, a quiter linear, but at least, the "a linear supply is always quiter than a switcher" is disproven.

I am aware, this is where the regulator follows a switcher, but todays power factor regulations almost makes the transformer/recifier "first supply" a thing of the past.
