Hello all. I just downloaded a circuit simulator from here:
http://www.newburytech.co.uk/Pages/download.html
I would like to simulate the PSU below but I noticed that there is no spice model for an LED. Does anyone know where I could find one? Yes I have searched using google and have had no luck. I've never used a simulator before. Any advice is appreciated.

spice model for an LED
I have never found one and I have hundreds of spice models.
I doubt you are going to find very decent models for the regulators either just go build thing. It should be fine.

Depending on the color and manufacturer, you may end up with an equation that looks a bit like V= 1.97 + 0.08 log(I) + 20I. Good luck.
