9.2.1.2.1 Input Capacitor Selection

TI recommends a minimum input capacitance (including DC bias effects) of 5 µF. A 10-µF, 10-V ceramic capacitor is suitable for typical applications. If the input supply is located more than a few centimeters from the converter, you may need to add additional bulk capacitance (a 47-µF electrolytic or tantalum capacitor is a typical choice).

The output capacitance does not have an upper limit; you can make it as big as you want.
