spice simulation - expert advice needed - RF Cafe Forums

Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views. It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if you would like to post something on RF Cafe's Facebook page, please do.

Below are all of the forum threads, including all the responses to the original posts.

Simulating a Voltage Regulator spice model - Performing Transient analysis with Voltage regulator loaded with current source set with 20KHx pulse input. Voltage regulator is a fixed 5V regulator.
When I measure the regulator output after the simulation it seems to be stable.

When i load the regulator with a LPF and then run a similar simulation I see the regulator output to be ringing?

can anyone throw some light on whats happening in this situation?

Any help in this regard would be much appreciated
