GENERAL DESCRIPTION

The ADP3334 is a member of the ADP333x family of precision low dropout anyCAP voltage regulators. The ADP3334 operates with an input voltage range of 2.6 V to 11 V and delivers a continuous load current up to 500 mA. The novel anyCAP architecture requires only a very small 1 µF output capacitor for stability, and the LDO is insensitive to the capacitor’s equivalent series resistance (ESR). This makes the ADP3334 stable with any capacitor, including ceramic (MLCC) types for space restricted applications.
