TABLE 2: ELECTRICAL TEST REQUIRE E TS

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.

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

Note 4: Guaranteed by design, characterization, or correlation to other

tested parameters.

data sheet. For compliance with 883 revision C current density

specifications, the RH1084 is rated to 3A.
