The inductor and the output capacitor together provide a low-pass filter. To simplify the selection process, Table 9-3 outlines possible inductor and capacitor value combinations for most applications.

(1) Typical application configuration. Other '+' mark indicates recommended filter combinations.
(2) Inductor tolerance and current derating is anticipated. The effective inductance can vary by 20% and
(3) Capacitance tolerance and bias voltage derating is anticipated. The effective capacitance can vary by 20% and –50%.
