ADP3334

T he 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. T he novel anyCAP

architecture requires only a very small 1 µF output capacitor for

stability, and the LDO is insensitive to the capacitor’s equiva-

lent series resistance (ESR). This makes ADP3334 stable with any

capacitor, including ceramic (MLCC) types for space restricted

applications.

Figure 1. Typical Application Circuit

T he ADP3334 achieves exceptional accuracy of ±0.9% at room

temperature and ±1.8% over temperature, line, and load. T he

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

500 mA. T his 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. T he

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

load situations.

T he ADP3334 also features ADI’s thermally enhanced T hermal

Coastline package. This allows 1 W of power dissipation without

any external heat sinking.
