Notes:
(1 Specification for 2.85V output version unless specified otherwise.
(2) Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at
1V differential. During test, the input voltage stays always above the minimum 2.3V.
(3) Specification for 1.8V output version.
(4) For VOUT < 2.0V, the initial accuracy is ±2% and across temperature ±3%.
