GENERAL DESCRIPTION

The ADP3330 is a member of the Analog Devices, Inc., precision

low dropout (LDO) anyCAP® voltage regulator family of products.

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 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 minimum output capacitor of

0.47 µF for stability. This device is insensitive to output capacitor

equivalent series resistance (ESR), and is stable with any good

quality capacitor, 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 an ultralow

ground current 34 µA (typical) in light load situations.

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

Analog Devices proprietary chip-on-lead feature to maximize

power dissipation.
