ADP3331: High Accuracy, Ultra-Low Quiescent Current LDO; SOT-23
Product Description
The ADP3331 is a member of the ADP330x family of precision low dropout anyCAP™ voltage regulators. The ADP3331 operates with an input voltage range of 2.9 V to 12 V and delivers a load current up to 200 mA. The ADP3331 stands out from the conventional LDO's with a novel architecture and an enhanced process which enables it to offer performance advantages and higher output current than its compeititon. Its patented design requires only a 0.47 µF output capacitor for stability. This device is insensitive to capacitor Equivalent Series Resistance (ESR), and is stable with any good quality capacitor, including ceramic (MLCC) types for space restricted applications. The ADP3331 achieves exceptional accuracy of ± 0.7% at room temperature and ± 1.4% overall accuracy over temperature, line and load variations. The dropout voltage of the ADP3331 is only 140 mV (typical) at 200 mA. This device also includes a safety current limit, thermal overload protection and a shutdown feature. In shutdown mode, the ground current is reduced to less than 2 µA. The ADP3331 has ultralow quiescent current 34 µA (typical) in light load situations. The SOT-23-6 package has been thermally enhanced using Analog Device's proprietary Chip-on-Lead™ feature to maximize power dissipation.
