GENERAL DESCRIPTION
The ADP3330 is a member of the ADP330x family of precision
low dropout anyCAP voltage regulators. The ADP3330 operates
with an input voltage range of 2.9 V to 12 V and delivers a load
current up to 200 mA. The ADP3330 stands out from the con-
ventional 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 0.47
F output capacitor for stability. This
device is insensitive to output capacitor Equivalent Series
Resistance (ESR), and is stable with any good quality capaci-
tor, including ceramic (MLCC) types for space-restricted
applications. The ADP3330 achieves exceptional accuracy of
0.7% at room temperature and
1.4% over temperature, line
and load variations. The dropout voltage of the ADP3330 is
only 140 mV (typical) at 200 mA. This device also includes a
safety current limit, thermal overload protection and a shutdown
feature. In shutdown mode, the ground current is reduced to
less than 2
A. The ADP3330 has ultralow quiescent current
34
A (typ) 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 ADP3330 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.
