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 architecture, an enhanced process and a new package. Its patented design requires only a 0.47 F output capacitor for stability. This device is insensitive to capacitor Equivalent Series Resistance (ESR) and is stable with any good quality capacitor, 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.
