13.12 Main and Standby Load Transient Response
The waveform shows the instantaneous output voltage for 33% to 66% step load change.
The voltage step change is under 50 mV for Standby output and under 150 mV for Main
output. For the Standby test the Main output was off, for the Main test the Standby output
was loaded at 50%.
