GENERAL DESCRIPTION
The ADP3331 is a member of the ADP330x family of preci-
sion low dropout anyCAP voltage regulators. The ADP3331
operates with an input voltage range of 2.6 V to 12 V and deliv-
ers a load current up to 200 mA. The ADP3331 stands out
from the conventional LDOs with a novel architecture and an
enhanced process that enables it to offer performance advan-
tages and higher output current than its competition. Its pat-
ented design requires only a 0.47 F output capacitor for
stability. This device is insensitive to capacitor Equivalent
Series Resistance (ESR), and is stable with any good quality
capacitor, including ceramic (MLCC) types for space restricted

applications. The ADP3331 achieves exceptional accuracy of
temperature, line and load variations. The dropout voltage of
the ADP3331 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 ADP3331 has ultralow quies-
cent current 34 A (typical) in light load situations. The
SOT-23-6 package has been thermally enhanced using Analog
Device’s proprietary Chip-on-Lead feature to maximize power
dissipation.
