Product Number: LT3012
Software Version: LTspice 24.1.9
I tried running the LTspice FRA tool on a model a LT3012 circuit and the output was a much lower 0 crossing and phase margin than I expected. I'd be a bit concerned with this circuit if it were a SMPS control loop.
This is calling into question that stability of the LDO
First, is the LT3012 spice model really built in such a way that the FRA simulation should produce an accurate bode plot?
Second are there special consideration I should take into account running a FRA of an LDO?
