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.
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.

OUT

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