GENERAL DESCRIPTION
The ADP3339 is a member of the ADP33xx family of precision
low dropout anyCAP voltage regulators. The ADP3339 operates with an input voltage range of 2.8 V to 6 V and delivers a
load current up to 1.5 A. The ADP3339 stands out from the
conventional LDOs with a novel architecture and an enhanced
process that enables it to offer performance advantages and
higher output current than its competition. Its patented design
requires only a 1.0 µF output capacitor for stability. This device
is insensitive to output capacitor Equivalent Series Resistance
(ESR), and is stable with any good quality capacitor, including
ceramic (MLCC) types for space-restricted applications. The
ADP3339 achieves exceptional accuracy of ±0.9% at room
temperature and ± 1.5% over temperature, line and load variations. The dropout voltage of the ADP3339 is only 230 mV
(typical) at 1.5 A. This device also includes a safety current limit
and thermal overload protection. The ADP3339 has ultralow
quiescent current 130 µA (typical) in light load situations.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the ADP3339 features proprietary ESD protection circuitry, permanent damage may occur on
devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.
