The parts you want to simulate are NEVER included in the libraries. I'm looking for the models in the subject. Anyone know where to find them??

need to get a datasheet? (LM317)
got one here for you.
do you know anything about an IC C4106??

Just some hints & tips of voltage regulators-They have considerable internal gain and thus to ensure unconditional high-frequency stability, it is recommended that relatively low value (say 100nf or so) capacitors be fitted (from input to ground and from output to ground) as close as possible to the regulator.

In the vast majority of applications, voltage regulators will operate at significant power levels. it is thus essential to provide adequate heat sinking (following the manufacturer's recommendations). Failure to observe this precaution may result in premature current limiting or out put voltage foldback due to thermal shutdown.

With regard to C4106 do a google search under the heading semiconductor data sheets. You would be surprised of the outcome.

cheers!
