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 3: The LTM8005 contains over-temperature protection that is
intended to protect the device during momentary overload conditions. The
internal temperature exceeds the maximum operating junction temperature
when the over-temperature protection is active. Continuous operation
above the specified maximum operating junction temperature may impair
device reliability.
Note 2: The LTM8005E is guaranteed to meet performance specifications
from 0°C to 125°C internal. Specifications over the full –40°C to
125°C internal operating temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTM8005I is guaranteed to meet specifications over the full –40°C
to 125°C internal operating temperature range. The LTM8005MP is
guaranteed to meet specifications over the full –55°C to 125°C internal
operating temperature range. The LTM8005H is guaranteed to meet
specifications over the full –40°C to 150°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.
