The is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3303 stands out from the conventional LDOs with a novel architecture, an enhanced process and a new package. Its patented design requires only 0.47 µF output capacitor for stability. This device is insensitive to capacitor Equivalent Series Resistance (ESR) and is stable with any good quality capacitor, including ceramic types (MLCC) for space restricted applications. The ADP3303 achieves exceptional accuracy 0.8% at room temperature and ± 1.4% overall accuracy over temperature, line and load regulations. The dropout voltage of the ADP3303 is only 180 mV (typical) at 200 mA. In addition to the new architecture and process, ADI's new proprietary thermally enhanced package (Thermal Coastline) can handle W of power dissipation without external heatsink or large copper surface on the PC board. This keeps PC board real estate to a minimum and makes the ADP3303 very attractive for use in portable equipment. The ADP3303 operates with a wide input voltage range from 12 V and delivers a load current in excess of 200 mA.
It features an error flag that signals when the device is about to lose regulation or when the short circuit or thermal overload protection is activated. Other features include shutdown and optional noise reduction capabilities. The ADP330x anyCAP LDO family offers a wide range of output voltages and output current levels: ADP3300 (50 mA, ADP3301 (100 mA) ADP3302 (100 mA, Dual Output) ADP3307 (100 mA, ADP3308 (50 mA, ADP3309 (100 mA, SOT-23-5)

*This is a stress rating only; operation beyond these limits can cause the device to be permanently damaged.
Function Output of the Regulator. Bypass to ground with µF or larger capacitor. Pins 1 and 2 must be connected together for proper operation. Noise Reduction Pin. Used for reduction of the output noise. (See text for details.) No connection if not used. Ground Pin. 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. Open Collector Output. Goes low to indicate that the output is about to go out of regulation. Regulator Input. Pins 7 and 8 must be connected together for proper operation.Contact the factory for the availability of other output voltage options. *SO = Small Outline.

NOTES 1 See individual data sheets for detailed ordering information. SO = Small Outline, SOT = Surface Mount.
CAUTION ESD (electrostatic discharge) sensitive device. Electrostatic charges as high 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADP3303 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.
