Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
Note 2: The LT3782E is guaranteed to meet performance speci?cations
from 0°C to 85°C. Speci?cations over the –40°C to 125°C operating
junction temperature range are assured by design, characterization and
meet performance speci?cations over the full –40°C to 125°C operating
junction temperature range.
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 speci?ed maximum operating junction
temperature may impair device reliability.
