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. The ADP1752 is available in seven fixed output voltage options. The ADP1753 is the adjustable version， which allows output voltages that range from 0.75 V to 3.3 V via an external divider. The ADP1752/ADP1753 allow 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. The ADP1752/ADP1753 are available in a 16-lead， 4 mm × 4 mm LFCSP， making them not only very compact solutions， but also providing excellent thermal performance for applications that require up to 800 mA of output current in a small， low profile footprint.
