Overview
The ADP150ACBZ-2.5-R7, produced by Analog Devices Inc., is an ultralow noise, low dropout, linear regulator. This device 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 designed with an innovative circuit topology that achieves ultralow noise performance of 9 µV rms, independent of the output voltage, without the need for an additional noise bypass capacitor. This makes it ideal for noise-sensitive analog and RF applications. The ADP150 also optimizes battery life in portable applications due to its low quiescent current and low shutdown current.
