I have not tried these out but have been intrigued by the
ripple-rejection specs of some of the newer regulators: LT3045 and
LT3094 for example. The datasheet explicitly refers to post-filtering
of SMPS as an application for these devices and the ripple rejection
curve looks very good. Not the most DIY-friendly package (MSOP) but we
don't worry about that nowadays do we?

Only 500mA capability but allegedly the design means they can be run
in parallel for more current. One day I will experiment...
