Overview
The ADP7104ARDZ-5.0-R7 is a CMOS, low dropout linear regulator (LDO) produced by Analog Devices Inc. This high input voltage LDO operates from 3.3 V to 20 V and provides up to 500 mA of output current. It is designed for the regulation of high-performance analog and mixed-signal circuits operating from 19 V to 1.22 V rails. The regulator features an advanced proprietary architecture that ensures high power supply rejection, low noise, and excellent line and load transient response with a small 1 μF ceramic output capacitor.
