GENERAL DESCRIPTION ADP7102ARDZ

The ADP7102 is a CMOS, low dropout linear regulator that operates from 3.3 V to 20 V and provides up to 300 mA of output current. This high input voltage LDO is ideal for regulation of high performance analog and mixed signal circuits operating from 19 V to 1.22 V rails. Using an advanced proprietary architecture, it provides high power supply rejection, low noise, and achieves excellent line and load transient response with just a small 1 μF ceramic output capacitor.
