Notes

11.

Section “MODES OF OPERATION”, page 13 has a detailed description of the different operating modes of the 34713

12.

Design information only, this parameter is not production tested.

13.

The ±1% accuracy is only guaranteed for VEFOUT greater then or equal 0.7 V at room temperature.

14.

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