Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
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 (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
Note 5: Dropout voltage is specified over the full output current range of
the device. Test points and limits are shown on the Dropout Voltage curve.
Note 6: For LT1083 I FULL LOAD is 5A for – 55 ° C ≤ T J ≤ – 40 ° C and 7.5A for
T J ≥ – 40 ° C.
Note 7: 1.7V ≤ (V IN – V OUT ) ≤ 25V for LT1084 at – 55 ° C ≤ T J ≤ – 40 ° C.
Note 8: Dropout voltage 1.7V maximum for LT1084 at
– 55 ° C ≤ T J ≤ – 40 ° C.
Note 9: Full load current is not available at all input-output voltages.
See Notes 3, 4, 6.
the input/output differential and the output current. Guaranteed maximum
power dissipation will not be available over the full input/output range.
Note 4: I FULL LOAD is defined in the current limit curves. The I FULLLOAD
curve is defined as the minimum value of current limit as a function of
input to output voltage. Note that the 60W power dissipation for the
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.
