The ADP1752/ADP1753 are CMOS, low dropout linear regulators that operate from 1.6 V to 3.6 V and provide up to 800mA of output current. These low Vin / Vout LDOs are ideal for regulation of nanometer FPGA geometries operating from 2.5V down to 1.8V I/O rails, and powering core voltages down to 0.75V. Using an advanced proprietary architecture, they provide high power supply rejection, low noise, and achieve excellent line and load transient response with a small 4.7 µF ceramic output capacitor. The ADP1752 is available in 7 fixed output voltage options.The ADP1753 is available in an adjustable version, which allows output voltages that range from 0.75 V to 3.0 V via an external divider. The ADP1752/ADP1753 allows an external soft start capacitor to be connected to program the start-up. A power good output allows power system monitors to digitally check the health of the output power rail 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 requiring up to 800mA of output current in a small, low profile footprint.
