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 LT3590E is guaranteed to meet performance speci?cations
from 0°C to 85°C junction temperature. Speci?cations over the –40°C
to 85°C operating junction temperature range are assured by design,
characterization and correlation with statistical process controls.
