3.3 Load Transients

Load transient response is shown in the following waveforms. For Figure 3-19, the channels are identified with the following:

C1 = 12-V output, AC coupled, C4 = 12-V output current

For Figure 3-10, the channels are identified with the following:

C3 = 12-V output, AC coupled, C4 = 12-V output current
