Analog Devices Inc. ADP7112 Low Noise, CMOS LDO Linear Regulators

Analog Devices ADP7112 low noise, CMOS low dropout (LDO) linear regulators operate from 2.7V to 20V and offer up to 200mA of output current. Developed with an advanced proprietary architecture, ADP7112 delivers high power supply rejection, low noise, and excellent line & load transient response with a small 2.2µF ceramic output capacitor. ADP7112's output noise is 11μVrms independent of the output voltage for the fixed options of 5V or less.

The ADP7112 is ideal for the regulation of high-performance analog and mixed-signal circuits operating from 20V down to 1.2V rails. Available in a 6-ball 1mm × 1.2mm WLCSP package, the Analog Devices ADP7112 CMOS LDO linear regulators are well-suited for regulation to noise-sensitive applications, ADC, DAC circuits, precision amplifiers, power for VCO VTUNE control, communications & infrastructure, medical & healthcare, and industrial & instrumentation.
