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 LTM4615E is guaranteed to meet performance specifications

over the 0°C to 125°C internal operating temperature range. Specifications

over the –40°C to 125°C internal operating temperature range are assured

by design, characterization and correlation with statistical process

controls. The LTM4615I is guaranteed to meet specifications over the full

internal operating temperature range. Note that the maximum ambient

temperature is determined by specific operating conditions in conjunction

with board layout, the rated package thermal resistance and other

environmental factors.

Note 3: Minimum operating voltage required for regulation is:

Note 4: Dropout voltage is the minimum input to output differential needed

to maintain regulation at a specified output current. In dropout the output

Note 5: The IC has overtemperature protection that is intended to protect

the device during momentary overload conditions. Junction temperatures

will exceed 125°C when overtemperature is activated. Continuous

overtemperature activation can impair long-term reliability.
