O
= 0.1µF, unless otherwise specified.
Notes:
1. Load and line regulation are specified at constant junction temperature. Changes in V
o
due to heating effects must
be taken into account separately. Pulse testing with low duty is used.
2. These parameters, although guaranteed, are not 100% tested in production.
