ANALOG DEVICES ADP7159ACPZ-01-R7 LDO Voltage Regulator, Adjustable, 2.3 to 5.5V in, 1.2 to 1.8V / 2A Out, LFCSP-EP-10, -40 to 125 °C

ADP7159ACPZ-01-R7 is an adjustable linear regulator that operates from 2.3V to 5.5V and provides up to 2A of output current. Using an advanced proprietary architecture, the device provides high power supply rejection and ultralow noise, achieving excellent line and load transient response with only a 10?F ceramic output capacitor. The typical output noise of the ADP7159 regulator is 0.9?V rms from 100Hz to 100KHz and 1.7nV/?Hz for noise spectral density from 10KHz to 1MHz. Applications include regulation to noise sensitive applications: phase-locked loops (PLLs), voltage controlled oscillators (VCOs), and PLLs with integrated VCOs, communications and infrastructure, backhaul and microwave links.
