NOTE: -12V, +3.3V, +5V, +12V will have the regulation to +/-10% when all load take off.
The +3.3V and +5V total output shall not exceed 61 watts. The +3.3V,
+5V and +12V total output shall not exceed 165 watts and the total
output for this subject power supply is 180 watts. Ripple and noise
measurements shall be made under all specified load conditions
through a single pole low pass filter with 20MHz cutoff frequency.
Outputs shall bypassed at the connector with a 0.1uF ceramic disk
capacitor and a 10uF electrolytic capacitor to simulate system loading.
