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 15W for RH1086MK and 3W for the RH1086MH. 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^®1086 data sheet.
Note 4: Guaranteed by design, characterization, or correlation to other
tested parameters.
Note 5: I_{FULL LOAD} is defined in the Current Limit curves in the standard
data sheet. For compliance with 883 revision C current density
specifications, the RH1086MK is derated to 1A.

PDA Test Notes
The PDA is specified as 5% based on failures from group A, subgroup 1,
tests after cooldown as the final electrical test 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 for the lot.
Linear Technology Corporation reserves the right to test to tighter limits
than those given.
