1.2.1 Input and Output Capacitors

C5 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.

C8 and C9 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. For output voltages higher than 5 V, more output capacitance is necessary. The total output capacitance must remain within the recommended range in Data sheet title for proper operation.
