Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
Current Measurements are performed when the LTC3525L-3 is not may cause permanent damage to the device. Exposure to any Absolute switching. Maximum Rating condition for extended periods may affect device
Note 5:
This IC includes overtemperature protection that is intended reliability and lifetime. to protect the device during momentary overload conditions. Junction
Note 2:
The LTC3525LE-3 is guaranteed to meet performance temperature will exceed 125°C when overtemperature protection is active. specifications from 0°C to 85°C. Specifications over the –40°C to 85°C Continuous operation above the specified maximum operating junction operating temperature range are assured by design, characterization and temperature may impair device reliability. correlation with statistical process controls.
