Overview
The ADP7118WAUJZ-5.0-R7 is a CMOS, low dropout (LDO) linear regulator manufactured by Analog Devices Inc. This high input voltage LDO operates from 2.7V to 20V and provides up to 200mA of output current, making it ideal for regulating high performance analog and mixed-signal circuits operating from 19V down to 1.2V rails. The device features an advanced proprietary architecture that ensures high power supply rejection ratio (PSRR), low noise, and excellent line and load transient response with a small 2.2µF ceramic output capacitor.
