I use the below formula to calculate
Vout = (1+R1/R2) x Vref
= (1+105/K127K) x 1.25V
= 2.28V
But TINA simulation does not show the same with calculation.
it shows Vout = 1.25

Hello,
Which model are you using? I just ran the simulation using the TINA models from here and got 2.27V as the output for both the transient and AC models.
Here is a snapshot of the circuit and results:

Hi,
In order to add pictures to an E2E message you have to click on "Use rich formatting" on the bottom right of the message. Once you do that you will have the option to attach items to a message. The add picture icon (Insert/Edit Media) is right below the eraser icon.
If you are still having issues please send me a picture of you test schematic. I imported the PSPICE file into TINA from "slvm672.zip" and still got 2.27V.
Please make sure you are checking the voltage at the cathode, not the reference pin, and that the bias resistor (R1 in the schematic above) is set appropriately (between 19 Ohms and 2.73k Ohms for no load).

Dear Diego,
I try to attach TINA simulation file and screen capture in this reply.
If you don't see them please let me know so I can try again.
Thanks.
T. Nguyen.
