GENERAL DESCRIPTION
The ADP1740/ADP1741 are low dropout (LDO) CMOS linear
regulators that operate from 1.6 V to 3.6 V and provide up to 2 A
of output current. These low V IN /V OUT LDOs are ideal for regu-
lation 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 ADP1740/
ADP1741 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 ADP1740 is available in seven fixed output voltage options.
The ADP1741 is an adjustable version that allows output
10nF
Figure 2. ADP1741 with Adjustable Output Voltage, 0.75 V to 3.3 V
voltages ranging from 0.75 V to 3.3 V via an external divider.
The ADP1740/ADP1741 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 ADP1740/ADP1741 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 applica-
tions that require up to 2 A of output current in a small, low
profile footprint.
