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: This µModule regulator includes overtemperature protection that
is intended to protect the device during momentary overload conditions.
Internal temperature will exceed 125°C when overtemperature protection
is active. Continuous operation above the specified maximum internal
operating junction temperature may impair device reliability.

Note 3: The LTM8052E is guaranteed to meet performance specifications
from 0°C to 125°C internal operating temperature. Specifications over the
full –40°C to 125°C internal operating temperature range are assured by
design, characterization and correlation with statistical process controls.
The LTM8052I is guaranteed to meet specifications over the full –40°C
to 125°C internal operating temperature range. Note that the maximum
internal temperature is determined by specific operating conditions in
conjunction with board layout, the rated package thermal resistance and
other environmental factors.
