Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The LT3028 regulator is tested and specified under pulse load
conditions such that T J ≈ T A . The LT3028E is guaranteed to meet
performance specifications from 0 ° C to 125 ° C junction temperature.
range are assured by design, characterization and correlation with
statistical process controls. The LT3028I is guaranteed and tested over the
full – 40 ° C to 125 ° C operating junction temperature range.
Note 3: The LT3028 is tested and specified for these conditions with the
ADJ1/ADJ2 pin connected to the corresponding OUT1/OUT2 pin.
