Here is the resulting Gain/Phase for a live power supply delivering 2.5A out, at 5V:
Click the button on the Spectrum Display to show the Gain and Phase Margin Markers. Notice the Phase
Margin is 53.7 degrees, which is in the optimum range, while the Gain Margin is -10 dB which is adequate in
allowing for component and temperature variation whilst ensuring stability.
The gain at low frequencies is upward of 55 dB. The relatively small bandwidth of about 1 kHz (gain >20 dB)
means output capacitors will be required if there is a current demand at higher frequencies.
