Typical Application Circuit GENERAL DESCRIPTION The ADP3303A 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 a 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 of ± 0.8...
