Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The LTM8049E is guaranteed to meet performance specifications from 0°C to 125°C. Specifications over the –40°C to 125°C internal temperature range are assured by design, characterization and correlation with statistical process controls. LTM8049I 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. Note 3: 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 4: CLKOUTn is intended to drive other circuitry. Do not apply a positive or negative voltage or current source to CLKOUT, otherwise permanent damage may occur. Note 5: The duty cycle of CLKOUT2 is dependent upon the internal temperature. See the Applications Information section for more details. The l denotes the specifications which apply over the specified operating temperature range (Notes 2, 3), otherwise specifications are at TA = 25°C. RUN = 2V unless otherwise specified.
