spice simulation - expert advice needed - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

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
