Product Introduction

Overview

The ADM7150ACPZ-3.3-R2 is a high-performance, low dropout (LDO) linear regulator produced by Analog Devices Inc. This regulator operates from an input voltage range of 4.5 V to 16 V and provides up to 800 mA of output current. It is designed using an advanced proprietary architecture that ensures high power supply rejection ratio (PSRR), ultralow output noise, and excellent line and load transient response. The ADM7150 is available in various fixed output voltage options, with the ADM7150ACPZ-3.3-R2 specifically providing a fixed output voltage of 3.3 V.
