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. The device also includes a safety current limit
and thermal overload protection. The ADP3339 has ultralow
quiescent current: 130 μA (typical) in light load situations.
