Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LT3710E is guaranteed to meet performance specifications
from 0 ° C to 125 ° C. Specifications over the – 40 ° C to 125 ° C operating
temperature range are assured by design, characterization and correlation
Note 3: This IC includes overtemperature protection that is intended to
protect the device during momentary overload conditions. Junction
temperature will exceed 125 ° C when overtemperature protection is active.
Continuous operation above the specified maximum operating junction
temperature may impair device reliability.
