The is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3303A stands out from conventional LDOs with a novel architecture, an enhanced process and a new package. Its patented design requires only 1 µF output capacitor for stability. This device is insensitive to output capacitor ESR (Equivalent Series Resistance), and is stable with any good quality capacitor, including ceramic types (MLCC) for space restricted applications. The ADP3303A achieves exceptional accuracy 0.8% at room temperature and ± 1.4% overall accuracy over temperature, line and load variations. The dropout voltage of the ADP3303A is only 150 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 an external heat sink or large copper surface on the PC board. This keeps PC board real estate to a minimum and makes the ADP3303A very attractive for use in portable equipment. The ADP3303A operates over an input voltage range 12 V and delivers a load current in excess of 200 mA. The output voltage can be adjusted from 10 V using an external resistor divider. It also 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.

Function No Connect. Output of the Regulator. Bypass to ground with µF or larger capacitor. Pins 4 and 5 must be connected together for proper operation. Feedback. Connect to an external resistor divider that sets the output voltage. Ground. 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 that goes low to indicate that the output is about to go out of regulation. Regulator Input. Pins 10 and 11 must be connected together for proper operation. No Connect.9 Comments High Accuracy High Accuracy Dual Output High Accuracy High Accuracy High Accuracy

NOTES All devices operate over the ambient temperature range to +85°C. 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 ADP3303A 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.
