Has anyone here saw this: http://www.digikey.com/product-highlights/us/en/micrel-ripple-blocker/3036 Seems that someone decided to put an active filter in a CI.... tried making this sort of circuit before but no luck.... i´ll buy some to see if a canned solution works better. Daniel

Hi, with a 3.6 volts maximum input it is of limited use for most of our old equipment.

Yes but it can be usefull to make new equipment :) Daniel Em 12/05/2013 03:57, m k escreveu: > Hi, > > with a 3.6 volts maximum input it is of limited use for most of our old equipment. > > M K > >> Date: Sun, 12 May 2013 00:02:47 -0300 >> From: dmendesf@gmail.com >> To: volt-nuts@febo.com >> Subject: [volt-nuts] Micrel Ripple Blocker >> >> >> Has anyone here saw this: >> >> http://www.digikey.com/product-highlights/us/en/micrel-ripple-blocker/3036 >> >> Seems that someone decided to put an active filter in a CI.... tried >> making this sort of circuit before but no luck.... i´ll buy some to see >> if a canned solution works better. >> >> Daniel >> _______________________________________________ >> volt-nuts mailing list -- volt-nuts@febo.com >> To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts >> and follow the instructions there. > > _______________________________________________ > volt-nuts mailing list -- volt-nuts@febo.com > To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/volt-nuts > and follow the instructions there.

The Micrel datasheet shows a pretty standard source follower configuration. I checked similar low dropout/low noise regulators from Linear Technology and they have similar output noise and power supply rejection.

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: http://www.engineeringtv.com/video/Micrel-Understanding-RippleBloc;Micrel-Videos "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." -- http://blog.softwaresafety.net/ http://www.designer-iii.com/ http://www.wearablesmartsensors.com/
