NOTE: 4. Channel under test shall follow the specified conditions while the other channel is set to min load, 0A.
5. Channel under test shall be set to full load with the other channel set to IO, min - See Fig 2 for the
recommended output ripple and noise test setup.
6. Refer to YSC plots on Fig 19 and 20 to determine loop stability at various output load impedance.
