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 mF 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

Figure 1. Typical Application Circuit
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 mA. The ADP3331 has
ultralow quiescent current 34 mA (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.
