Customer is looking for the 3.3V LP3990 PSPICE simulation.
Looking in the product folder, there is no specified pspice for 3.3V. Is there a reason about this?
Thank you in advance.

It's likely that this voltage option did not exist when the original models were made. The gain of the internal amplifier changes with a new setpoint. So you can update an unencrypted model, such as the 1.2V unencrypted model, for 3.3V. Change R_R3 to be 80k and leave R_R4 alone.
