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 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 µF output capacitor 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 ultralow quiescent current 34 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.

1 OUT Output of the Regulator. Bypass to ground
with a 0.47 µF or larger capacitor.
2 IN Regulator Input. 3 ERR Open Collector Output that goes low to
indicate that the output is about to go out
of regulation. 4 GND Ground Pin. 5 NR Noise Reduction Pin. Used for further
reduction of output noise (see text for
detail). No connection if not used. 6 SD Active Low Shutdown Pin. Connect to
ground to disable the regulator output.
When shutdown is not used, this pin
should be connected to the input pin.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADP3330 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
