Note 1: Unless otherwise specified, these specifications apply for

is internally limited, these specifications are applicable for power

the TO-39 and 1.5A for the TO-3 package.

Note 2: Regulation is measured at a constant junction temperature using

pulse testing with a low duty cycle. Changes in output voltage due to

heating effects are covered under the specification for thermal regulation.

Note 3: Guaranteed by design, characterization or correlation to other

tested parameters.

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.
