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
