4.1.3 Input and Output Capacitors

C9, shown in Figure 5-1, Figure 5-2, Figure 5-3, and Figure 5-4, is provided for an additional input capacitor. This capacitor is not required for proper operation, but can be used to reduce the input voltage ripple and to reduce the input impedance created by the input supply cables.

C6, C7, and C8 are provided for additional output capacitors. These capacitors are not required for proper operation but can be used to reduce the output voltage ripple and to improve the load transient response. The total output capacitance must remain within the recommended range in the data sheet for proper operation.
