GENERAL DESCRIPTION  
The ADP3303 is a member of the ADP330x family of precision  
low dropout anyCAP1 voltage regulators. The ADP3303 stands  
out from the conventional LDOs with a different architecture,  
an enhanced process, and a different package. 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  
types (MLCC) for space restricted applications. The ADP3303  
achieves exceptional accuracy of 0.8% at room temperature  
and 1.4% overall accuracy over temperature, line, and load  
regulations. The dropout voltage of the ADP3303 is only  
180 mV (typical) at 200 mA.  
The ADP3303 operates with a wide input voltage range from  
3.2 V to 12 V and delivers a load current in excess of 200 mA.  
It features an error flag that signals when the device is about to  
lose regulation or when the short circuit or thermal overload  
protection is activated. Other features include shutdown and  
optional noise reduction capabilities. The ADP330x anyCAP  
LDO family offers a wide range of output voltages and output  
current levels:

In addition to the architecture and process, the Analog Devices,  
Inc., proprietary thermally enhanced package (Thermal Coastline)  
can handle 1 W of power dissipation without external heatsink  
or large copper surface on the printed circuit board (PCB). This  
keeps PCB real estate to a minimum and makes the ADP3303  
very attractive for use in portable equipment.
