GENERAL DESCRIPTION

The ADP1752/ADP1753 are low dropout (LDO) CMOS linear regulators that operate from 1.6 V to 3.6 V and provide up to 800 mA 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, they 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.
