ELECTRICAL OPERATING CHARACTERISTICS
V
operating conditions unless specified otherwise). Bold numbers apply for the entire junction temperature range.
.
Notes:
(1) Specification for 2.8V 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.
