Overview
The ADP150AUJZ-2.8-R7, produced by Analog Devices Inc., is an ultralow noise, low dropout linear regulator designed for high-performance, noise-sensitive analog and RF applications. This regulator operates from an input voltage range of 2.2 V to 5.5 V and provides up to 150 mA of output current. It is particularly suited for battery-operated portable equipment due to its low quiescent current and shutdown current consumption. The ADP150AUJZ-2.8-R7 is available in a compact 5-lead TSOT package, making it ideal for space-constrained designs.
