For Compliance with the Current Density specifictation of MIL-STD-883 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 25W. 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/ Dropout voltage is tested by reducing input voltage until the output drops 1% below its nominal value. Tests are done at 0.5A and 3A. The power transistor looks basically like a pure resistance in this range so that minimum differential at any intermediate current can be calculated by interpolation; VDROPOUT = 0.25V + (0.25 x IOUT). For load current less than 0.5A, see Figure 4. 7/ "Minimum input voltage" is limited by base emitter voltage drive of the power transistor section, not saturation as measured in Note 6. For output voltages below 4V, "minimum input voltage" specification may limit dropout voltage before transistor saturation limitation. 8/ Supply current is measured on the ground pin, and does not include load current, RLIM, or output divider current. 9/ The 25W power level is guaranteed for an input-output voltage of 8.3V to 17V. At lower voltages the 3A limit applies, and at higher voltages the internal power limiting may restrict regulator power below 25W. 10/ Line and load regulation are measured on a pulse basis with a pulse width of 2ms, to minimize heating. DC regulation will be affected by thermal regulation and temperature coefficient of the reference. 11/ VSAT is the maximum specified dropout voltage; 0.25V +(0.25 x IOUT). 12/ Current limit is programmed with a resistor from REF pin to GND pin. RLIM = 15K/ILIM 15K/ILIM. 13/ Pulsed @ 2µF Tantalum.
