Overview
The ADM7150ACPZ-5.0-R2 is a high-performance, low dropout (LDO) linear regulator produced by Analog Devices Inc. This regulator is designed to operate from an input voltage range of 4.5 V to 16 V and provides a fixed output voltage of 5 V with a maximum output current of 800 mA. It is particularly noted for its ultralow noise and high power supply rejection ratio (PSRR), making it suitable for noise-sensitive applications.
