GENERAL DESCRIPTION
The ADP3306 is a member of the ADP330x family of precision low dropout anyCAP™ voltage regulators. The ADP3306 stands out from the conventional LDOs with a novel architecture, an enhanced process and a new package. Its patented design requires only a 0.1 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 ADP3306 achieves exceptional accuracy of ±1.0% at room temperature and ±1.5% overall accuracy over temperature, line and load regulations. The dropout voltage of the ADP3306 is only 300 mV (typical) at 300 mA.
