Typical Application
Note:
C
i
is required when regulator is located an appreciable distance from power supply filter.
Note:
C
o
is not needed for stability, however, it does improve transient response.
Note:
Since I
ADJ
is controlled to less than 100
P
A, the error associated with this term is negligible in most applications.
