Typical Application Circuit GENERAL DESCRIPTION The ADP3307 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3307 stands out from the conventional LDOs with a novel architecture and an enhanced process. Its patented design requires only a 0.47 µF output capacitor for stability. This device is stable with any type of capacitor regardless of its ESR (Equivalent Series Resistance) value, including ceramic types (MLCC) for space restricted applications. The ADP3307 achieves exceptional accuracy of ± 0.8% at room temperature and ± 1.4% overall...
