General Description

EC87XX 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 lowdropout linear regulator.
The EC87XX operates from an input voltage of VOUT+1V to 40V, consumes only 2.6μA of quiescent current, and offers 1% initial accuracy and SoftStart function.
At power startup, the output voltage overshoot is less than 100mV.
The EC87XX regulators is available in standard SOT89-3L, and SOT23-3L packages.
