8.2.2.5 Output Capacitance

The amount of required output capacitance depends on the output voltage setting, as shown in Table 3. For an output voltage of 1.2 V, the required minimum output capacitance is 200 µF, with a requirement that at least 47 µF must be ceramic type.

In this application, a combination of a 200 µF of ceramic capacitance and a 220 µF bulk capacitor was used. The additional 220 µF bulk capacitor will help in applications with fast changing load current.
