9.2.2.3 Output Capacitor Selection

For the output capacitor, it is recommended to use of small ceramic capacitors placed as close as possible to the VOUT and PGND pins of the IC. The recommended nominal output capacitors are three times 22 µF. If, for any reason, the application requires the use of large capacitors that cannot be placed close to the IC, use a smaller ceramic capacitor in parallel to the large capacitor. Place the small capacitor as close as possible to the VOUT and PGND pins of the IC.

There are no additional requirements regarding minimum ESR. There is also no upper limit for the output capacitance value. Larger capacitors cause lower output voltage ripple as well as lower output voltage drop during load transients.
