The ADP7118ARDZ-3.3-R7 is a fixed output, CMOS low dropout (LDO) linear regulator in 8 pin NSOIC package. This high input voltage LDO is ideal for the regulation of high performance analogue and mixed signal circuits operating from 20V down to 1.2V rails. Using an advanced proprietary architecture, the device provides high power supply rejection, low noise and achieves excellent line and load transient response with a small 2.2μF ceramic output capacitor. Each fixed output voltage can be adjusted above the initial set point with an external feedback divider.
