| Sep 30, 2013 at 19:36 | comment | added | Scott Winder | The voltage regulator cannot respond instantaneously to changes in power requirements, resulting in a momentary dip in voltage when current demands increase. The capacitors charge to the output voltage level of the regulator, and then supply localized current while the regulator adjusts to meet the demands on the power rail. The capacitors are placed as near as possible to the current sink to minimize the resistive effects of the trace (or wire) connecting the IC to the supply. | |

All whining aside, could you post your design IC name and links to the datasheets you're using? I've seen often that the IC design recommends components (some go as specific as the component maker). Did your datasheet not include this? If you could post a few additional details, such as part number, PCB layout/schematic, components you would like to use, I think you could get more specific answers. | |
