ADP1755 1.2A Low-Vin, Adjustable-Vout LDO Linear Regulator
The ADP1754/ADP1755 are CMOS, low dropout linear regulators that operate from 1.6 V to 3.6 V and provide up to 1.2A of output current. These Low Vin / Vout LDOs are ideal for regulation of nanometer FPGA geometries operating from 2.5V 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 ADP1754 is available in seven fixed output voltage options. The ADP1755 is available in an adjustable version, which allows output voltages that range from 0.75 V to 3.3 V via an external divider. The ADP1754/ADP1755 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 ADP1754/ADP1755 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 1.2A of output current in a small, low profile footprint.
