Overview
The ADP150AUJZ-3.3-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 a fixed output voltage of 3.3 V with a maximum output current of 150 mA. The ADP150 is notable for its ultralow noise performance of 9 µV rms, which is independent of the output voltage, and does not require an additional noise bypass capacitor. This makes it ideal for use in battery-operated portable equipment and other applications where low noise and high efficiency are critical.
