ADP7118AUJZ-4.5-R7

ADP7118AUJZ-4.5-R7 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 analogue and mixed-signal circuits operating from 19V down to 1.2V rails. Using an advanced proprietary architecture, this device provides high power supply rejection, low noise, and achieves excellent line and load transient response with a small 2.2µF ceramic output capacitor. The ADP7118 regulator output noise is 11μV rms independent of the output voltage for fixed options of 5V or less. Applications include regulation for noise-sensitive applications such as ADC and DAC circuits, precision amplifiers, power for VCO VTUNE control, communications and infrastructure, medical and healthcare, industrial, and instrumentation.
