ANALOG DEVICES ADP7156ARDZ-1.8-R7 LDO Voltage Regulator, Fixed, 2.3 to 5.5V in, 1.8V / 1.2A Out, NSOIC-EP-8, -40 to 125 °C

ADP7156ARDZ-1.8-R7 is a linear regulator operating from 2.3V to 5.5V, capable of providing up to 1.2A of output current. Utilizing an advanced proprietary architecture, it offers high power supply rejection and ultralow noise, achieving excellent line and load transient response with just a 10µF ceramic output capacitor. Applications include regulation for noise-sensitive systems such as phase-locked loops (PLLs), voltage-controlled oscillators (VCOs), PLLs with integrated VCOs, as well as communications and infrastructure, including backhaul and microwave links.
