Product Introduction

Overview

The ADP151ACPZ-1.8-R7 is an ultralow noise, low dropout (LDO) linear regulator produced by Analog Devices Inc. This device is designed to operate from an input voltage range of 2.2 V to 5.5 V and can provide up to 200 mA of output current. It 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 bypass capacitor. The ADP151 is available in several compact package options, including 5-lead TSOT, 6-lead LFCSP, and 4-ball WLCSP, making it ideal for space-constrained and portable power applications.
