ADP7156 Overview
The ADP7156 is a linear regulator that operates from 2.3 V to 5.5 V and provides up to 1.2 A of output current. Using an advanced proprietary architecture, it provides high power supply rejection and ultralow noise, achieving excellent line and load transient response with only a 10 µF ceramic output capacitor. There are 16 standard output voltages for the ADP7156.
