LT1083 (45W for the LT1084 (K, P), 30W for the LT1084 (T), 30W for the
LT1085) is only achievable over a limited range of input to output voltage.

Dropout voltage is specified over the full output current range of
the device. Test points and limits are shown on the Dropout Voltage curve.

The
G
denotes the specifications which apply over the full operating
temperature range.
Note 1:
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 2:
Line and load regulation are guaranteed up to the maximum power
dissipation (60W for the LT1083, 45W for the LT1084 (K, P), 30W for the
LT1084 (T) and 30W for the LT1085). Power dissipation is determined by
the input/output differential and the output current. Guaranteed maximum
power dissipation will not be available over the full input/output range.
Note 3:
I
FULL LOAD
is defined in the current limit curves. The I

curve is defined as the minimum value of current limit as a function of
