STANDARD APPLICATION
* C

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.

Notes:
1. Load and Line Regulation are specified at a constant junction temperature. Pulse testing with low duty cycle is used.
Changes in output voltage due to heating effects must be taken into account separately.
2. If not tested, shall be guaranteed to the specified limits.
3. The
denotes the specifications which apply over the full operating temperature range.
