Note 1:
All parameters tested at T
A
= +25°C. Limits through the temperature range are guaranteed by design.
Note 2:
Not production tested. Guaranteed by design.
Note 3:
Turn-on time (also called soft-start time) is defined as the difference in the time between when the output crosses 10%, and
90% of the final output voltage.
