Thank you everyone for viewing my inquire.
I was thinking the other day while driving about using a dual power supply that would output 5v and 3.3v. now I use decoupling caps on both the vdd in and the dual vdd out but can someone tell me if I need to use decoupling caps on my vdd, gnd for ic like microcontrollers etc that are on the regulated side of the volt regulater as the volt reg has been decoupled? I was not sure if, that it is regulated already, you should not see the spikes you would see on the mains vdd input and not need the extra caps.
Thanks for your help.
