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.
This expert design tool produces custom DC-DC converter designs in about a minute. The user enters 5 inputs and chooses to optimize for efficiency, PCB space, cost, or part count. Output is a complete schematic, BOM, efficiency plot, and performance summary. A PDF summary and a blank PCB is offered for each design to facilitate fast prototyping to verify the design.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
