GENERAL DESCRIPTION

The ADP3330 is a member of the Analog Devices, Inc., precision low dropout (LDO) anyCAP® voltage regulator family of products. The ADP3330 operates with an input voltage range of 2.9 V to 12 V and delivers a load current up to 200 mA. The ADP3330 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 minimum output capacitor of 0.47 µF for stability. This device is insensitive to output capacitor equivalent series resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for space restricted applications.
