ADP3303: High Accuracy anyCAP® 200 mA Low Dropout Linear Regulator
Product Description
The ADP3303 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 architec-ture, an enhanced process and a new package. Its patented design requires only a 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 ADP3303 achieves exceptional accuracy of ±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 1 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 3.2 V to 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 from 50 mA to 200 mA:
ADP3300 (50 mA, SOT-23)
ADP3301 (100 mA)
ADP3302 (100 mA, Dual Output)
