Peter,
Could you provide any additional information about the simulation issue with the LDO? If Kirchoff's current law is not satisfied at a node, does the simulaiton converge? Is there anything special about the power down state? For example, does the circuit have hystersis in the control loop? Are you performing a dc operating point calculation or a dc sweep? If the simulation is just a dc operating point, you can try using the simulator option gmethod=both. If you are running from inside the environment, you can tirn off all the homotopy and manually set homotopy=arclength.
Best Regards,
Sheldon
