Note 2: The LT3483E is 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 is guaranteed to meet specifications over the –40°C to

125°C operating temperature range.

Note 3: Current flows out of the pin.
