GENERAL DESCRIPTION
The ADP3338 is a member of the ADP33xx family of precision
low dropout anyCAP voltage regulators. The ADP3338 oper-
ates with an input voltage range of 2.7 V to 8 V and delivers a
load current up to 1 A. The ADP3338 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
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
ADP3338 achieves exceptional accuracy of
±
0.8% at room
temperature and
±
1.4% over temperature, line and load varia-
tions. The dropout voltage of the ADP3338 is only 190 mV
(typical) at 1 A. This device also includes a safety current limit
and thermal overload protection. The ADP3338 has ultralow
quiescent current 110
μ
A (typical) in light load situations.
