(3)
The voltage rating of the input capacitor must be selected for the desired operating input voltage range of the regulator. To operate the
regulator at a higher input voltage, select a capacitor with the next higher voltage rating.
(4)
Not reccomended (N/R). The voltage rating does not meet the minimum operating limits in most applications.
(5)
The maximum rating of the ceramic capacitor limits the regulator's operating input voltage to 20 V. Select a alternative ceramic
component to operate at a higher input voltage.
(6)
A total capacitance of 2 F is an acceptable replacement value for a single 2.2-F ceramic capacitor.
