ADP7118ACPZN-R7

ADP7118 is a CMOS, low dropout (LDO) linear regulator that 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 19V 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 setpoint with an external feedback divider. This allows the ADP7118 to provide an output voltage from 1.2 V to VIN − VDO with high PSRR and low noise. Applications includes regulation to noise sensitive applications, communications and infrastructure, medical and healthcare, industrial and instrumentation.

• Typical operating supply current of 180µA at IOUT = 200mA
