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 LT3483E/LT3483AE are guaranteed to meet specifications from
0°C to 85°C. Specifications over the –40°C to 85°C operating temperature
range are assured by design, characterization and correlation with
statistical process controls. The LT3483I/LT3483AI are guaranteed to meet
specifications over the –40°C to 125°C operating temperature range.
Note 3: Current flows out of the pin.
