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.

... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the ADP3334 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...
