Overview
The ADP7118AUJZ-5.0-R7 is a high-performance, low dropout (LDO) linear regulator produced by Analog Devices Inc. This regulator operates from an input voltage range of 2.7 V to 20 V and provides a fixed output voltage of 5 V with a maximum output current of 200 mA. The ADP7118 is designed using an advanced proprietary architecture, which ensures high power supply rejection, low noise, and excellent line and load transient response. It is particularly suited for regulating high-performance analog and mixed-signal circuits.
