8.4.4 Output Capacitor Selection (Buck Converter)

For best output voltage filtering a low ESR output capacitor is recommended. Typically, four 10-µF (or two 22-µF) ceramic output capacitors work for most of the applications. Higher capacitor values can be used to improve the load transient response. Refer to the Recommended Operation Conditions table, Table 8-3 and the Typical Application section for input capacitor recommendations.
