in the case of capacitors used for ripple filtering in the input and output of a voltage regulator, the values used are usually given according to device datasheet ratings. Say for example a LM7805 needs 0.47uF at the input side and 100nF at the output side.
Is it possible to know the charging and discharging time? Say example for the input capacitor (0.47uF) , we know that tau=RC. and we have C.. what would be the equivalent R then?
Thanks
