STANDARD APPLICATION
* CIN is required if regulator is located an
appreciable distance from power supply filter.
** Co is not needed for stability, however it does
improve transient response.

Since IAdj is controlled to less than 100 µA,
the error associated with this term is negligible
in most applications.
