CIN : More than 0.33 F required if regulator is located an appreciable distance from power supply filter.

You must use to prevent from the parasitic oscillation.

COUT : More than 47 F. You must use the Low-impedance-type(low ESR) capacitor.

CIN : More than 0.33 F required if regulator is located an appreciable distance from power supply filter.
