Descriptions

 

EC85XX 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 EC85XX operates from an input voltage of VOUT+1V to 35V, consumes only 2.6μA of quiescent current, and offers 2% initial accuracy and low dropout voltage, 300mV typical at 100mA.

 

EC85XX has 1.8V2.5V3.0V3.3V3.6V4.0V4.2V5.0V fixed voltage versions. Other features include short-circuit protection and thermal shutdown.
