8.2.2.4.3 Output Capacitor

One of the major parameters necessary to define the capacitance value of the output capacitor is the maximum allowed output voltage ripple of the converter and device stability. Internal device compensation defines the limits for the capacitance on the output. Only ceramic capacitors like X7R, X5R or equivalent are recommended. Table Table 8 gives the minimum amount of capacitors required for a given output voltage based on the dc bias effect. For lowest output voltage ripple, more capacitance can be added up to the maximum value as defined in the recommended operating conditions.
