Note 1: See thermal regulation specifications for changes in output voltage
due to heating effects. Line and load 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 of 45W for RH1084. Power dissipation is determined by the
input/output differential voltage and the output current. Guaranteed
maximum power dissipation will not be available over the full input/output
voltage range.
Note 3: Dropout voltage is specified over the full output current range of
the device. Test points and limits are shown on the Dropout Voltage curve
in the LT®1084 data sheet.
Note 4: Guaranteed by design, characterization, or correlation to other
tested parameters.
Note 5: IFULL LOAD is defined in the Current Limit curves in the standard
data sheet. For compliance with 883 revision C current density
specifications, the RH1084 is rated to 3A.

PDA Test Notes
The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown in accordance with method 5004 of MIL-STD-883
Class B. The verified failures of group A, subgroup 1, after burn-in divided
by the total number of devices submitted for burn-in in that lot shall be
used to determine the percent defective for the lot.
Linear Technology Corporation reserves the right to test to tighter limits
than those given.
Information furnished by Linear Technology Corporation is believed to be accurate and reliable.

tation that the interconnection of its circuits as described herein will not infringe on existing patent rights.
