Product Introduction

Overview

The ADP3338AKC-3.3-RL, produced by Analog Devices Inc., is a high-accuracy, ultralow quiescent current, 1 A anyCAP® low dropout (LDO) voltage regulator. This device is part of the ADP33xx family and stands out from conventional LDOs with its novel architecture and enhanced process, offering superior performance and higher output current. The ADP3338 operates with an input voltage range of 2.7 V to 8 V and delivers a load current up to 1 A, making it suitable for a variety of applications requiring high precision and low dropout voltage.
