Hi,-- something that is bothering me for quite some time now--Most of the regulator datasheets(78XX for eg) say that an input capacitor to the regulator is required to be connected if the dc unregul. voltage source is at a far away distance from the regulator. Is this true ??
If it is then what are the calculations that go into it?
I thought that the most imp. factor while choosing the cap. value would be the ripple factor (assuming known load current,o/p voltage, freq )
