Overview
The ADM7150ACPZ-3.3-R7 is a high-performance, ultralow noise, high power supply rejection ratio (PSRR) linear regulator developed by Analog Devices Inc. This device operates within an input voltage range of 4.5 V to 16 V and provides a fixed output voltage of 3.3 V with a maximum output current of 800 mA. The ADM7150 is designed using an advanced proprietary architecture, ensuring excellent line and load transient response and low dropout voltage. It is available in compact 8-lead LFCSP and SOIC packages, making it suitable for applications requiring high current in a small footprint.
