ADP7118 / ADP7142 CMOS LDO Linear Regulators

Analog Devices Inc. ADP7118 CMOS low dropout (LDO) linear regulator operates from 2.7V to 20V and provides up to 200mA of output current. This high input voltage LDO is ideal for the regulation of high-performance analog and mixed-signal circuits operating from 20V down to 1.2V rails. ADP7142 operates from 2.7V to 40V and provides up to 200mA of output current. This high input voltage LDO is ideal for the regulation of high-performance analog and mixed-signal circuits operating from 40V down to 1.2V rails. Using an advanced proprietary architecture, ADI ADP7118 and ADP7142 devices provide high power supply rejection, low noise, and achieve excellent line and load transient response with a small 2.2μF ceramic output capacitor. Regulator output noise is 11μV rms independent of the output voltage for the fixed options of 5V or less.
