"Dr. Chris Gator explains Micrel's Ripple Blocker technology, and
provides a demonstration of how this noise-attenuating software works.
This video was produced at the APEC 2012 show in Orlando, FL. "

Says blocks ripple to 10 MHz most other regulators are specified at 10
or 100 kHz for PSRR.  Anyone know of where to find the full length
version rather than this intro?

Longer version:

"Micrel's Carlos Huerta explains Ripple Blocker, a power supply noise
attenuator from Micrel. This product reduces or eliminates power
supply noise that can interfere with all kinds of electronic
devices--from cellphones to GPS units, from medical scanning devices
to cameras."
