Figure 102. Open-Loop Gain and Phase TINA-TI™ Simulation Setup
This test is set up with a very light load to isolate the no load A_OL curve. Adding a load brings in the open-loop
Z_OL response to the overall response of the output pins. Running this simulation gives the gain and phase of
Figure 103 that closely matches the plot of Figure 37.
