Overview
The ADP7118AUJZ-2.5-R7 is a CMOS, 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 up to 200 mA of output current. It is designed for the regulation of high-performance analog and mixed-signal circuits, offering excellent line and load transient response with a small 2.2 µF ceramic output capacitor. The device is particularly noted for its low noise and high power supply rejection ratio (PSRR), making it ideal for various applications requiring stable and precise voltage regulation.
