GENERAL DESCRIPTION
●The ADP1754/ADP1755 are low dropout (LDO) CMOS linear regulators that operate from 1.6 V to 3.6 V and provide up to 1.2 A of output current. These low VIN/VOUT LDOs are ideal for regulation of nanometer FPGA geometries operating from 2.5 V down to 1.8 V I/O rails, and for powering core voltages down to 0.75 V. Using an advanced proprietary architecture, the ADP1754/
●ADP1755 provide high power supply rejection ratio (PSRR) and low noise, and achieve excellent line and load transient response with only a small 4.7 µF ceramic output capacitor.
