Note 2: The LT3585 series is guaranteed to meet performance
specifi cations from 0°C to 85°C. Specifi cations over the – 40°C to 85°C
operating temperature range are assured by design, characterization and
correlation with statistical process controls.
Note 3: Current limit is guaranteed by design and/or correlation to static
test.
