I am trying to find worst case gain and phase margins in a design using the TPS7A4501-SP. I am using the PSpice model from tps7a4501-sp_wca.lib. When doing a 50 run Monte Carlo analysis, the phase jumps -360 degrees for some of the runs. Is this expected? Can I safely add 360 degrees to those runs for the analysis? The phase response looks as follows:
