Product Introduction

Overview

The ADP151ACBZ-1.2-R7, produced by Analog Devices Inc., is an ultralow noise, low dropout (LDO) linear regulator. This device operates from an input voltage range of 2.2 V to 5.5 V and provides up to 200 mA of output current. It is designed for stable operation with small 1 µF ceramic input and output capacitors, making it ideal for high-performance, space-constrained applications. The ADP151 is particularly suited for noise-sensitive analog and RF applications due to its innovative circuit topology that achieves ultralow noise performance without the need for a noise bypass capacitor.
