ANALOG DEVICES ADP7158ACPZ-1.2-R7 LDO Voltage Regulator, Fixed, 2.3 to 5.5V in, 1.2V / 2A Out, LFCSP-EP-10, -40 to 125 °C

ADP7158ACPZ-1.2-R7 is a linear regulator that operates from 2.3V to 5.5V and provides up to 2A of output current. Using an advanced proprietary architecture, it provides high power supply rejection and ultralow noise, achieving excellent line and load transient response with only a 10µF ceramic output capacitor. The ADP7158 regulator's typical output noise is 0.9?V rms from 100Hz to 100KHz and 1.7nV/?Hz for noise spectral density from 10KHz to 1MHz. Applications include regulation for noise-sensitive applications such as phase-locked loops (PLLs), voltage-controlled oscillators (VCOs), PLLs with integrated VCOs, communications infrastructure, backhaul, and microwave links.
