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. During test, the
input voltage stays always above the minimum 2.3 V.
5. Specification for 1.8 V output version.
6. For V OUT < 2.0 V, the initial accuracy is ± 2% and across temperature ± 3%.
