The ADP7142ARDZ-R7 is a low dropout (LDO) Linear Regulator that operates from 2.7 to 40V and provides up to 200mA of output current. This high input voltage LDO is ideal for the regulation of high performance analogue and mixed signal circuits operating from 40V 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. It is available in 16 fixed output voltage options. Each fixed output voltage can be adjusted above the initial set point with an external feedback divider. This allows the regulator to provide an output voltage from 1.2V to VIN - VDO with high PSRR and low noise.
