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

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