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.

The ADP3334 achieves exceptional accuracy of ±0.9% at room

temperature and ±1.8% over temperature, line, and load. The

dropout voltage of the ADP3334 is only 200 mV (typical) at

500 mA. This device also includes a safety current limit, ther-

mal overload protection, and a shutdown feature. In shutdown

mode, the ground current is reduced to less than 1 µA. The

ADP3334 has low quiescent current of 90 µA (typical) in light

load situations.
