ELECTRICAL OPERATING CHARACTERISTICS
V
recommended operating conditions unless specified otherwise). Bold numbers apply for the entire junction
temperature range.
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
(3) Specification for 1.8V output version.
(4) For VOUT < 2.0V, the initial accuracy is ±2% and across temperature ±3%.
