Except for "brute force" power supplies, depending on the capactors to
perform filtering only works on steady state conditions, which except for
test bench measurements quite often do not exsist in a real application.
The large capacitors are placed on the raw DC supply before the regulator
circuit. Smaller ones are place on the other side. Although the capacitors
do lower ripple, they have terrible response to dynamic load swings (which
is the job of the active regulator).
