Notes :
(1) To specify an output voltage. substitute voltage value for "XX." A common ground is required between the input and the
Output voltage. The input voltage must remain typically 2.0V above the output voltage even during the low point on the input
ripple voltage.
(2) C I is required if regulator is located an appreciable distance from power Supply filter.
(3) C O improves stability and transient response.
