Note 1:
Absolute Maximum Ratings are those values beyond which the life maximum output power will not be available over the full input/output of a device may be impaired. voltage range.
Note 2:
See thermal regulation specifications for changes in output voltage
Note 4:
IFULL LOAD is defined as the maximum value of output load current due to heating effects. Load and line regulation are measured at a constant as a function of input-to-output voltage. IFULL LOAD is equal to 7A for the junction temperature by low duty cycle pulse testing. LT1584, 4.6A at TJ ≥ 25°C and 4A at TJ < 25°C for the LT1585/LT1585-3.3 and 3A for the LT1587.

Line and load regulation are guaranteed up to the maximum power 4A. dissipation (25W for the LT1584 in T package, 26.5W for the LT1585 in T The LT1585 and LT1587 have constant current limit with changes in input-to-output voltage. The LT1584 has variable current limit which package, 18W for the LT1587 in T package). Power dissipation is decreases about 4A as input-to-output voltage increases from 3V to 7V. determined by input/output differential and the output current. Guaranteed 158457a 5
