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 per device. 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/ Dropout voltage is specified over the full output current rang e of th e de vi ce .
5/ Not tested. Shall be guaranteed by design, characterization, or correlation to other tested parameters.
