TPS7A33: VREF Vs temperature clarifications for TPS7A33.

1. The limits for VREF at 25'C are specified from -1.192V to -1.157V. Does this include manufacturing, other variations at 25'C?

Yes, the limits in the EC table account for process variation at Tj = 25 degC

2. Fig-1 has temperature variations but again those doesn't match with limits given in datasheet. So now question is what are limits over temperature considering manufacturing, other variations?

Please note that test conditions (CIN and COUT) are different for figure 1 than the EC table and the junction temperature is now not held constant. That said, the EC table figures are more conservative so please refer to those.

3. Is this correct in fig-1 that shift at 85'C is more than 125'C? 

Yes, this is what was observed in validation. I will confirm it for you with our validation team to rule out an erroneous entry in the datasheet.
