Overview
The ADP7118ACPZN2.5-R7 is a CMOS, low dropout (LDO) linear regulator produced by Analog Devices Inc. This high-input-voltage LDO operates from 2.7V to 20V and provides up to 200mA of output current. It is designed for the regulation of high-performance analog and mixed-signal circuits, operating from 19V down to 1.2V rails. The device features high power supply rejection, low noise, and excellent line and load transient response with a small 2.2µF ceramic output capacitor. The regulator's output noise is 11μV rms for fixed output voltages of 5V or less, making it suitable for noise-sensitive applications such as ADC and DAC circuits, precision amplifiers, and VCO VTUNE control.
