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%.
