Overview
The ADP151ACBZ-1.8-R7 is an ultralow noise, low dropout (LDO) linear regulator produced by Analog Devices Inc. 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 to achieve ultralow noise performance without the need for a noise bypass capacitor, making it ideal for noise-sensitive analog and RF applications. The ADP151 is also optimized for use with small 1 µF ceramic input and output capacitors, making it suitable for high-performance, space-constrained applications.
