(1)
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.
(2)
The maximum voltage rating of the capacitor must be selected for the desired set-point voltage (VO ). To operate at a higher output
voltage, select a capacitor with a higher voltage rating.
(3)
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.
(4)
A total capacitance of 2 F is an acceptable replacement value for a single 2.2-F ceramic capacitor
