GENERAL DESCRIPTION

The ADPL44002 is a CMOS, low dropout (LDO) linear

regulator that operates from 2.7V to 40V and provides up

to 200mA of output current. This high input voltage LDO

is ideal for the regulation of high performance analog

and mixed signal circuits operating from 39V down to

1.2V rails. Using an advanced proprietary architecture,

the device provides high power supply rejection, low

noise, and achieves excellent line and load transient

response with a small 2.2µF ceramic output capacitor.

The ADPL44002 regulator output noise is 20μVRMS

independent of the output voltage for the fixed options

of 5V or less.

The ADPL44002 is available in four fixed output voltage

options. The following voltages are available from stock:

1.2V (adjustable), 1.8V, 2.5V, 3.3V, and 5.0V.

Each fixed output voltage can be adjusted above the

initial set point with an external feedback divider. This

allows the ADPL44002 to provide an output voltage from

1.2V to VIN − VDO with high PSRR and low noise.

User programmable soft start with an external capacitor

is available in the LFCSP package.

The ADPL44002 is available in a 6-lead, 2mm × 2mm

LFCSP, making it not only a very compact solution, but

it also provides excellent thermal performance for

applications requiring up to 200mA of output current in

a small, low profile footprint. The ADPL44002 is also

available in a 5-lead TSOT.
