So my questions is how do I calculate what capacitor to use when I want to smooth things out?Preemptive thanks to everyone who can help me or point me towards good info elsewhere.
Personally I tend to use 2 capacitors on the output instead of one.I use the typical 10µF, 22µF or whatever cap. I alsu add a much smaller cap in the range of 100nF. This allows for filtering out of high frequency noise which the big capacitor doesn't.Also, you should choose capacitors which have a low ESR.
Does the smaller cap really do anything?
