The is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3300 stands out from 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 capacitor, regardless of its ESR (Equivalent Series Resistance) value, including ceramic types (MLCC) for space restricted applications. The ADP3300 achieves exceptional accuracy 0.8% at room temperature and ± 1.4% overall accuracy over temperature, line and load variations. The dropout voltage of the ADP3300 is only 80 mV (typical) at 50 mA. The ADP3300 operates with a wide input voltage range from 12 V and delivers a load current in excess of 50 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 200 mA: ADP3301 (100 mA) ADP3302 (100 mA, Dual Output) ADP3303 (200 mA)anyCAP is a registered trademark of Analog Devices Inc.

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 or 5 volts output voltage. Bypass to ground with µF or larger capacitor. Regulator Input Open Collector Output which goes low to indicate that the output is about to go out of regulation.

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 ADP3300 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.
