I'd like to add additional capacitance to the output of a 5V 9A and 6A versions of the D24V90F5 step down regulator. This is for an RC application where digital servos will be noisy and cause potential voltage spikes on the output. I know some switching regulators are sensitive to adding capacitors straight to the output. I'd likely like to add 2 x 220uF caps. Can this be done safely, to achieve better smoothing/filtering on the output?
