GENERAL DESCRIPTION
The ADP3331 is a member of the ADP330x family of precision
low dropout anyCAP voltage regulators. The ADP3331 operates
with an input voltage range of 2.6 V to 12 V and delivers 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 advantages and higher
output current than its competition. Its patented design requires
only a 0.47 m F output capacitor for stability. This device is insensi-
tive to capacitor equivalent series resistance (ESR), and is stable
with any good quality capacitor, including ceramic (MLCC) types
REV. B

for space restricted applications. The ADP3331 achieves excep-
tional accuracy of ± 0.7% at room temperature and ± 1.4% overall
accuracy over temperature, line, and load variations. The drop-
out voltage of the ADP3331 is only 140 mV (typical) at 200 mA.
This device also includes a safety current limit, thermal over-
load protection, and a shutdown feature. In shutdown mode, the
ground current is reduced to less than 2 m A. The ADP3331 has
ultralow quiescent current 34 m 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 maxi-
mize power dissipation.
