I am trying to simulate the LT3099 with a pre-regulator, but there are weird patterns that appear in the simulation, so I reverted back to the LT3099 model exemple.
I have found that the VIOC output does not match what it is suppose to be. The .op sim always returns 0V at the pin, and the transient simulation does not shows VIOC = Vdo when a fixed dropout is applied (for exemple, a -8V input and -3.3V output leads to a -1.3V VIOC)
Is there a problem with the model?
