Overview
The ADP7159ACPZ-01-R7 is a high-performance, adjustable linear voltage regulator produced by Analog Devices Inc. This component is designed to operate from an input voltage range of 2.3 V to 5.5 V and can provide up to 2 A of output current. It is particularly noted for its ultra-low noise and high power supply rejection ratio (PSRR), making it suitable for noise-sensitive applications.
