Overview
The ADP7118ACPZN-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 high-performance analog and mixed-signal circuits, offering excellent line and load transient response with a small 2.2 µF ceramic output capacitor. The ADP7118 is available in various fixed output voltage options, ranging from 1.2 V to 5.0 V, and can be adjusted to higher voltages using an external voltage divider.
