In the initial design stage, the main question is how much phase margin is sufficient for reliable performance over process variation and temperature. If the phase margin of the initial implementation is not sufficient, multiple compensation schemes are available to increase the phase margin to an acceptable level. These solutions are given through pre-configured, easy-to-use projects in PSpice for TI. Finally, if there is a project already in production that does encounter a stability issue, use the drop-in solution proposed.
