TPS562231: Is it possible to get the VREF measurement data of -40°C/125°C with n=100?

Part Number: TPS562231

Dear application team

Customer ask us below.

Could you give me answer?

I would like to know something about T.I's buck converter TPS562231.

We are currently considering the adoption of this item in a new product.
From the datasheet (p7, Fig.2), we can confirm that the temperature characteristics of VREF is positive.
Even if VREF at room temperature varies, is it still positive temperature characteristics?

In addition, we would like to grasp the ability value of the temperature characteristics of VREF to some extent.
Is it possible to get the VREF measurement data of -40°C/125°C with n=100?
