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.

The ADP1754 is available in seven fixed output voltage options.

The ADP1755 is the adjustable version, which allows output

voltages that range from 0.75 V to 3.3 V via an external divider.

The ADP1754/ADP1755 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 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 that

require up to 1.2 A of output current in a small, low profile

footprint.
