The ME6203 series is an ultra-low static power low dropout linear regulator fabricated in CMOS technology.

Solution Introduction

The ME6203 series is an ultra-low static power low dropout linear regulator fabricated in CMOS technology.

Its working voltage is up to 40V. The circuit has built-in short circuit protection. This series of products can set a fixed output voltage through a built-in resistor feedback network, which can achieve 1.8V to 12V output. The output voltage accuracy is ±2% with a low temperature coefficient to ensure stable output voltage over the full temperature range.
