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 LT3517E is guaranteed to meet performance specifications

from 0°C to 125°C operating junction temperature range. Specifications

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

assured by design, characterization and correlation with statistical

process controls. The LT3517I is guaranteed over the full –40°C to 125°C

operating junction temperature range. The LT3517H is guaranteed over

the full –40°C to 150°C operating junction temperature range. Operating

lifetime is derated at junction temperatures greater than 125°C.

is 40V for nonrepetitive 1 second transients and 30V for continuous

operation.

Note 4: This IC includes overtemperature protection that is intended

to protect the device during momentary overload conditions. Junction

temperature will exceed the maximum operating junction temperature

when overtemperature protection is active. Continuous operation above

the specified maximum operating junction temperature may impair device

reliability.
