I have a project in which i have two 220uF capacitors in parallel with a servo motor. To help drive the thing. When I power on and off the device it seems to spaz out for a couple of minutes and sometimes it doesnt turn on. I have a MAX756 and feel that when I power down the device they discharge to the Max756 and microcontroller causing it to spaz out the servo. My question is, is this possible and if so would a diode before the 220uF capacitors resolve this?
Can you give a diagram of the whole circuit to help make things clear?

What's a .docx? 
My system just opens file roller as if it were an archive of some sort...

We like images.
JPEG, PNG - hell even ropey old BMP will do...
Connecting a 1K resistor from + Cap to - Cap will discharge the caps faster and shorten/eliminate some or all of your unusual issues...

It's a Word xml file, from 2007 on iirc. It is an archive of some sort: you can in fact undo the document to its constituent files with say 7-zip and then navigate to the images folder.
Peter you might like to be a bit clearer on exactly what spazzing out entails 8)
Docx files are word documents written materials. Started with Word 2007??? I don't remember for sure they can be opened successfully with Microsoft Word and Wordpad (usually, depends on embedded enabled features, A Lot.) and can contain pictures and drawings done in Paint, for example.

Sarcasm guys, Sarcasm. Don't get distracted by trolling comments.

Is this a good idea ? Is it an alternative to having separate servo power ?
