Hi Fredj,

We don't currently have a released model for the TLV709A33DBVR. As a workaround, I'd recommend using the TLV70950_TRANS model and modifying line 76 to the following:

R_R1_FB         FB OUT  1.74meg TC=0,0

Best Regards,

Hi Alex,

Your answer to Fredj was helpful for me in trying to model the adjustable variant of this regulator (TLV709A01). As you indicated, the output voltage can be adjusted by changing R_R1_FB. Taking this a step further, by removing both R_R1_FB and R_R2_FB from the model and exposing FB as a fourth pin, I can model the regular with an external resistor divider in my circuit.

My follow up question is wether making these changes to the TLV709A33 base model provides a reasonable approximation of the adjustable variant, or are there more significant differences that I'm missing?

Thanks!

Hi Zeke,

This should reasonably approximate the adjustable variant
