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 LTC3265 is tested under pulsed load conditions such that
T

≈ T
A
. The LTC3265E is guaranteed to meet specifications from
0°C to 85°C junction temperature. Specifications over the –40°C to
125°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls. The
LTC3265I is guaranteed over the –40°C to 125°C operating junction
temperature range, the LTC3265H is guaranteed over the –40°C to 150°C
operating junction temperature range and the LTC3265MP is guaranteed
over the –55°C to 150°C operating junction temperature range. High
