TPSM846C23: What is total accuracy of TPSM846C23

Part Number:TPSM846C23

I am interested in total accuracy across -40C..125C internal temperature.

If I follow the data sheet correctly it would be +-1.5% for setpoint plus  +-1% temp variation plus 0.2% load  reg plus 0.05 line reg giving total :+-2.75%.

Then tolerance of external Rset resistor should be added as well.

Is my interpretation of the data sheet correct ?

Thanks
