LM317: LM317

Part Number: LM317

Tool/software:

Hello, I downloaded the Pspice model and followed a tutorial (Import external models into LTSpice) on how to use it on my circuitry. Following the tutorial, I was able to use the ATL431A the same as the tutorial. And then i tried to use the same method to import LM317 as well as INA190A1 but have not been successful. The following errors are rising: 

For INA190A1: 

C:\Users\tesfuker\AppData\Local\LTspice\lib\sub\ina190a1.lib(374): Unknown parameter
GVCCS2_3 outz3 MID net3 MID -1}
^
C:\Users\tesfuker\AppData\Local\LTspice\lib\sub\ina190a1.lib(383): Unknown parameter
R7_4 outz3 MID R_NOISELESS 1 )

For LM317:

Can you please help me out on how I can fix the problem and use the models for circuit simmulations?

  • Hi Keriya,

    Unfortunately, we are unable to support LTSpice applications with our models due to licensing issues. That said, the issue you're experiencing with the LM317 model appears to be due to using the encrypted PSpice version of the model. Simulation tools other than PSpice should be able to import and simulate using the unencrypted version of the model

    Best Regards,
