The is a member of the ADP330x family of precision low dropout anyCAPTM* voltage regulators. The ADP3301 stands out from the conventional LDOs with a novel architecture, an enhanced process and a new package. Its patented design includes a noninverting wideband driver and a stage that permits the use of an internal "pole splitting" capacitor to stabilize the feedback loop with a single output capacitor as small as 0.47 µF. This device is stable with any type of capacitor regardless of its ESR (Equivalent Serial Resistance) value, including ceramic types (MLCC) for space restricted applications. The ADP3301 achieves exceptional accuracy 0.8% at room temperature and ± 1.4% overall accuracy over temperature, line and load regulations. The dropout voltage of the ADP3301 is only 100 mV (typical) at 100 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 heat sink or large copper surface on the PC board. This keeps PC board real estate to a minimum and makes the ADP3301 very attractive for use in portable equipment.
The ADP3301 operates with a wide input voltage range from 12 V and delivers a load current in excess of 100 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 anyCAPTM* LDO family offers a wide range of output voltages and output current levels from to 300 mA: ADP3300 (50 mA, ADP3302 (100 mA, Dual Output) ADP3304 (100 mA, Dual Output with Separate Grounds) ADP3303 (200 mA) ADP3306 (300 mA)

*This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operation section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
Function Output of the Regulator, fixed or 5 volts output voltage. Bypass to ground with µF or larger capacitor. Pins 1 and 2 must be connected together for proper operation. Noise Reduction Pin. Used for further 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 which 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.

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 ADP3301 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.
