Overview
The ADP3338AKCZ-1.8-R7, produced by Analog Devices Inc., is a high-performance, low dropout (LDO) voltage regulator belonging to the ADP33xx family. This device is designed to operate with an input voltage range of 2.7 V to 8 V and can deliver a load current of up to 1 A. It stands out for its novel architecture and enhanced process, offering superior performance and higher output current compared to conventional LDOs. The ADP3338AKCZ-1.8-R7 is particularly noted for its stability with any good quality capacitor, including ceramic types, and its ultralow quiescent current of 110 µA (typical) in light load situations.
