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

µF

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

µA.

The ADP3330 has ultralow quiescent current

µA

(typ) in light load situations.

The SOT-23-6 package has been thermally enhanced using

Analog Devices’ proprietary Chip-on-Lead feature to maximize

power dissipation.
