GENERAL DESCRIPTION  
The ADP3330 is a member of the Analog Devices, Inc., precision  
low dropout (LDO) anyCAP® voltage regulator family of products.  
The ADP3330 operates with an input voltage range of 2.9 V to  
12 V and delivers a load current up to 200 mA. The ADP3330  
stands out from the conventional LDOs with a novel architecture  
and an enhanced process that enables it to offer performance  
advantages and higher output current than its competition. Its  
patented design requires only a minimum output capacitor of  
0.47 µF for stability. This device is insensitive to output capacitor  
equivalent series resistance (ESR), and is stable with any good  
quality capacitor, including ceramic (MLCC) types for space  
restricted applications. The ADP3330 achieves exceptional  
accuracy of 0.7% at room temperature and 1.4% over  
temperature, line and load variations. The dropout voltage of  
the ADP3330 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 ADP3330 has an ultralow  
ground current 34 µA (typical) in light load situations.  
The 6-lead SOT-23 package has been thermally enhanced using  
Analog Devices proprietary chip-on-lead feature to maximize  
power dissipation.
