Overview
The ADP7159ACPZ-03-R7 is a high-performance, adjustable linear voltage regulator produced by Analog Devices Inc. This regulator is designed to operate over a wide input voltage range of 2.3 V to 5.5 V and can deliver up to 2 A of output current. It is particularly suited for applications requiring low noise, high power supply rejection ratio (PSRR), and excellent line and load transient response. The device features an advanced proprietary architecture that ensures stable and regulated output voltages from 1.2 V to 3.3 V, depending on the model configuration.
