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 V IN /V OUT 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.
