Overview
The ADP7118ARDZ-3.3-R7 is a high-performance, low dropout (LDO) linear regulator produced by Analog Devices Inc. This CMOS-based regulator is designed to operate from an input voltage range of 2.7 V to 20 V and provides a fixed output voltage of 3.3 V with a maximum output current of 200 mA. It is particularly suited for regulating high-performance analog and mixed-signal circuits due to its low noise, high power supply rejection ratio (PSRR), and excellent line and load transient response.
