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.

Below are the old forum threads, including 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

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a lady's voice announced "You've Got Mail" when a new message arrived...
