3. Specification for 2.80 V output version unless specified otherwise.

4. Dropout voltage is defined as the input−to−output differential at which the output voltage drops 2% below its nominal value measured at 1 V

differential. During test, the input voltage stays always above the minimum 2.3 V.

5. Specification for 1.8 V output version.

6. For VOUT < 2.0 V, the initial accuracy is ±2% and across temperature ±3%.
