Note 4: I
FULL LOAD
is defined as the maximum value of output load current
as a function of input-to-output voltage. I
FULL LOAD
is equal to 7A for the
LT1584, 4.6A at T
J
≥ 25°C and 4A at T
J
< 25°C for the LT1585/LT1585-3.3
and 3A for the LT1587. The remaining LT1585 fixed voltage versions are
4A.
The LT1585 and LT1587 have constant current limit with changes in
input-to-output voltage. The LT1584 has variable current limit which
decreases about 4A as input-to-output voltage increases from 3V to 7V.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a 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 LT1584 in T package, 26.5W for the LT1585 in T
package, 18W for the LT1587 in T package). Power dissipation is
determined by input/output differential and the output current. Guaranteed
