GENERAL DESCRIPTION
The ADP3339 is a member of the ADP33xx family of precision
low dropout anyCAP voltage regulators. The ADP3339 oper-
ates 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
μ
F 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 varia-
tions. 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
μ
A (typical) in light load situations.
