General Description

SE85XX series is designed for power-sensitive

applications. It includes a precision and high

voltage input stage, an ultra-low-power bias current

branch, and results in a ultra-low-power and

low-dropout linear regulator. The SE85XX operates from an input voltage of

VOUT+1V to 35V, consumes only 2.6μA of quiescent

current, and offers 1% initial accuracy and low dropout

voltage, 300mV typical at 100mA. SE85XX has 1.8V，2.5V，3.0V，3.3V，3.6V，

4.0V，4.2V，5.0V fixed voltage versions. Other features include short-circuit protection

and thermal shutdown.
