GENERAL DESCRIPTION
The ADP3331 is a member of the ADP330x family of precision low dropout anyCAP voltage regulators. The ADP3331 operates with an input voltage range of 2.6 V to 12 V and delivers a load current up to 200 mA. The ADP3331 stands out from the conventional LDOs with a novel architecture and an enhanced process that enables it to offer performance advantages and higher output current than its competition. Its patented design requires only a 0.47 µF output capacitor for stability. This device is insensitive to capacitor Equivalent Series Resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for space restricted applications.
