Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
The LTM8026E is guaranteed to meet performance specifications may cause permanent damage to the device. Exposure to any Absolute from 0°C to 125°C internal operating temperature. Specifications over the Maximum Rating condition for extended periods may affect device full –40°C to 125°C internal operating temperature range are assured by reliability and lifetime. design, characterization and correlation with statistical process controls.
Note 2:
This µModule regulator includes overtemperature protection that The LTM8026I is guaranteed to meet specifications over the full –40°C is intended to protect the device during momentary overload conditions. to 125°C internal operating temperature range. The LTM8026MP is Internal temperature will exceed 125°C when overtemperature protection guaranteed to meet specifications over the full –55°C to 125°C internal is active. Continuous operation above the specified maximum internal operating temperature range. Note that the maximum internal temperature operating junction temperature may impair device reliability. is determined by specific operating conditions in conjunction with board layout, the rated package thermal resistance and other environmental factors.
