The minimum required input capacitance network consists of four 22-µF (or two 47-µF) ceramic capacitors plus a 330-µF bulk capacitor. The minimum required output capacitance network consists of four 47-µF (or two 100-µF) ceramic capacitors plus two 470-µF, low ESR polymer capacitors. The combined ESR of the polymer capacitors must not be greater than 5 mΩ. Additional input and output capacitors can be added to improve ripple or transient response.
In this design example, the minimum required input and output capacitance is used.
