GENERAL DESCRIPTION

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.

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
