GENERAL DESCRIPTION
The ADP3303 is a member of the ADP330x family of preci-
sion low dropout anyCAP voltage regulators. The ADP3303
stands out from the conventional LDOs with a novel architec-
ture, an enhanced process and a new package. Its patented
design requires only a 0.47 F output capacitor for stability.
This device is insensitive to capacitor Equivalent Series Resis-
tance (ESR) and is stable with any good quality capacitor, in-
cluding 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.
In addition to the new architecture and process, ADI’s new
proprietary thermally enhanced package (Thermal Coastline)
can handle 1 W of power dissipation without external heatsink
or large copper surface on the PC board. This keeps PC board
real estate to a minimum and makes the ADP3303 very attrac-
tive for use in portable equipment.
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:
