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. CI is required if regulator is located an appreciable distance from power Supply filter.
3. CO improves stability and transient response.
