Notes:
1/ For Compliance with MIL-STD-883 Rev. C current density specification, the RH1086MK is derated to 1.0 Amp but is capable of 1.5Amps.
2/ Specification derated to reflect Total Dose exposure to 100Krad (Si) @ +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/ Dropout voltage is specified over the full output current range of the device.
5/ Not tested. Shall be guaranteed by design, characterization, or correlation to other tested parameters.
6/ Pulsed @ <10% duty cycle @ +25°C (See Note 1).
