ELECTRICAL CHARACTERISTICS

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 specifications

from 0°C to 85°C junction temperature. Specifications over the –40°C

to 85°C operating junction temperature range are assured by design,

characterization and correlation with statistical process controls.
