LM7805 & LM317 Orcad/Pspice Model?

post #1 of 6
Thread Starter 
Does anyone know of / have an Orcad Capture (Pspice) model for the voltage regulators? I looked around google and a few of the manufacturer sites and couldn't find anything. Unfortunately I don't know enough about Pspice to model it myself, and although I could make it from components according to the schematic, that might take forever.

Both should be in the standard opamp library.

But they're not.

Lt spice model for an LM317 - Electronic Circuits Projects Diagrams Free

These models seem to work, LM317 and LM337. You have to register to download.

For ORCAD 16.2, in .../CAPTURE/LIBRUARY/PSPICE/OPAMP.OLB, it has Pspice models for LM317H, LM317K,LM317T, LM7805C.

Yeah I'm remote desktop-ing into the university's network to use Orcad so I doubt the libraries are complete or in the right place - this opamp library doesn't have the LM series. Thanks for the link Nelson, I'll try it out.
