Notes:

1/ The manufacturer’s output current rating for the RH1084MK positive regulator integrated circuit is 5.0 Amps. For Compliance with

the Current Density specifictation of MIL-STD-883 Rev. C, the electrical performance characteristics are specified at an output

current of 3.0 Amps.

2/ Specification derated to reflect total dose exposure to 100krads (Si) at +25°C.

3/ Line and load regulation are guaranteed up to the maximum power dissipation of 15W. 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.

4/ Not tested. Shall be guaranteed by design, characterization, or correlation to other tested parameters.
