1.2.1 Input and Output Capacitors

C5 is provided for an input bulk capacitor. C1 and C2 are the additional bulk input capacitors and C3 and C4 are the input high-frequency bypass capacitors.

C16 and C17 are provided for additional bulk output capacitors for the first stage LC filter. C20, C21 and C22 are provided for additional bulk output capacitors for the second stage LC filter. These capacitors are not required for proper operation but can be used to reduce the output voltage ripple. The total output capacitance must remain within the recommended range in the data sheet for proper operation. C18 and C23 are provided for high-frequency bypass capacitors.
