(1) The values given for all the capacitors are effective capacitance, which includes the dc bias effect. Please check the manufacturer´s dc bias curves for the effective capacitance vs dc bias voltage applied.

(2) Larger values can be required if the source impedance can not support the transient requirements of the load.

(3) This is for capacitors directly at the output of the device. More capacitance is allowed if there is a series resistance associated to the capacitors. See also the systems examples Section 10.3.2 for applications with many distributed capacitors on the output.
