If the converter remains in regulation, the minimum output capacitance required is given by:
If the converter loop saturates, the minimum output capacitance is given by:
In this case, choose COUT(min) = 623 µF, as the larger of the two values, for the output capacitance.
When calculating worst-case component values, use the value calculated above as the minimum output capacitance required. For ceramic capacitors, the nominal capacitance when considering tolerance, DC bias, temperature, and aging effects is typically two times the minimum capacitance. In this case the nominal capacitance is thus 1246 µF.
