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 LT3596E is guaranteed to meet performance specifications
from 0°C to 125°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
LT3596I specifications are guaranteed over the full –40°C to 125°C
operating junction temperature range.
Note 3: For maximum operating ambient temperature, see the High
Temperature Considerations section in the Applications Information
section.
Note 4: Guaranteed by design.
