SPICE models for Vreg such as 78*** or LM3** series
Richard Leblanc
such as 78L05, 78L12, LM317, etc...
Is there a reason why any of the "full working" demo simulator do not carry
any??
When building a circuit and testing it on a simulator like Micro-CapVI,
should I assume that the output of such a device is immune to temperature
and that the ouput voltage is "flat"??
Best regards

Try the CircuitMaker evaluation program.

Here's a paste from my CircuitMaker Pro, for
