Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: See thermal regulation specifications for changes in output voltage
due to heating effects. Load and line regulation are measured at a constant
junction temperature by low duty cycle pulse testing.
Note 3: Line and load regulation are guaranteed up to the maximum
power dissipation (25W for the LT1585-1.5 in T package and 27.5W for
