Design information only, this parameter is not production tested. 16. Overall output accuracy is directly affected by the accuracy of the external feedback network, 1% feedback resistors are recommended 17. ±1% is assured at room temperature 18. The 1% output voltage regulation is only guaranteed for a common mode voltage range greater than or equal to 0.7V Table 3. Static Electrical Characteristics (continued) Characteristics noted under conditions 3.0 V ≤ V IN ≤ 6.0 V, -40°C ≤ T A ≤ 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. Characteristic Symbol Min Typ Max Unit |
