The is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3307 stands out from the conventional LDOs with a novel architecture and an enhanced process. Its patented design requires only 0.47 µF output capacitor for stability. This device is stable with any type of capacitor regardless of its ESR (Equivalent Series Resistance) value, including ceramic types (MLCC) for space restricted applications. The ADP3307 achieves exceptional accuracy 0.8% at room temperature and ± 1.4% overall accuracy over temperature, line and load regulations. The dropout voltage of the ADP3307 is only 120 mV (typical) at 100 mA. The ADP3307 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 anyCAP LDO family offers a wide range of output voltages and output current levels from to 300 mA: ADP3300 (50 mA, ADP3307 (100 mA, SOT) ADP3301 (100 mA, ADP3302 (100 mA, Dual Output) ADP3303 (200 mA) ADP3306 (300 mA)

Function Ground Pin. Noise Reduction Pin. Used for further reduction of the output noise. (See text for details.) No connection if not used. 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. Output of the Regulator, fixed 3.3 V output voltage. Bypass to ground with µF or larger capacitor. Regulator Input. Open Collector Output that goes low to indicate that the output is about to go out of regulation.Contact the factory for the availability of other output voltage options.

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 ADP3307 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.
