I've searched on this topic and got the answer that the input capacitor is there to remove any high frequency components. But the input to the regulator is mostly a DC input where does this frequency component comes from? One more reason that was given was stability, what stability are we talking about here?
Are ceramic capacitors any better than electrolytic capacitors in this respect? If yes, the why?
