(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 (V
O
). 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 µ F is an acceptable replacement value for a single 2.2- µ F ceramic capacitor
