General Description

CX85XX 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 CX85XX 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.

CX85XX 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.
