Static Regulation
Static output voltage variation measured at
output pins on system board with sense
pins connected to measured pins
1. Line Regulation
Output voltage variation as input voltage
changes from 5V to 12V with 50% load
2. Load Regulation
Output voltage variation as load changes
from 0% to 100%
