Has anybody investigated simple L-C (R-L-C) filters rather than linear
regulators?
The SI-List recently announced a good paper on using ferrite beads.

(Currently, it's the top paper. In case somebody finds this in the archives,
it's the one marked DesignCon 2011)
Page 5 of the slides has the critical graph. A ferrite bead is resistive
over a broad range of frequencies.
