Notes

16.

Design information only, this parameter is not production tested.

17.

Overall output accuracy is directly affected by the accuracy of the external feedback network, 1% feedback resistors are recommended

18.

±1% is assured at room temperature

19.

The 1 % output voltage regulation is only guaranteed for a common mode voltage range greater than or equal to 0.7V
