ADP1755ACPZ-R7 (ANALOG DEVICES)

The ADP1755ACPZ-R7 is a low VIN low dropout CMOS Linear Regulator that operates from 1.6 to 3.6V and provide up to 1.2A of output current. These low VIN/VOUT LDOs are ideal for regulation of nanometer FPGA geometries operating from 2.5 down to 1.8V I/O rails and for powering core voltages down to 0.75V. Using an advanced proprietary architecture, the ADP1755 provides high power supply rejection ratio (PSRR) and low noise and achieve excellent line and load transient response with only a small 4.7µF ceramic output capacitor. The ADP1755 is the adjustable version, which allows output voltages that range from 0.75 to 3.3V via an external divider. It allows an external soft start capacitor to be connected to program the startup. A digital power-good output allows power system monitors to check the health of the output voltage.
