Table 3. Static Electrical Characteristics
Characteristics noted under conditions 3.0 V ≤ VIN ≤ 6.0 V, -40°C ≤ TA ≤ 85°C, GND = 0 V unless otherwise noted. Typical
values noted reflect the approximate parameter means at TA = 25°C under nominal conditions unless otherwise noted.

Notes
11. Section “MODES OF OPERATION”, page 12 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 0.7V at room tempreature.
14. Overall output accuracy is directly affected by the accuracy of the external feedback network, 1% feedback resistors are recommended
