GENERAL DESCRIPTION
The ADP3303A is a member of the ADP330x family of preci-
sion low dropout anyCAP voltage regulators. The ADP3303A
stands out from the conventional LDOs with a novel architec-
ture, an enhanced process and a new package. Its patented
design requires only a 1
μ
F output capacitor for stability. This
device is stable with any capacitor regardless of its ESR (Equiva-
lent Series Resistance) value, including ceramic types (MLCC)
for space restricted applications. The ADP3303A achieves ex-
ceptional accuracy of
±
0.8% at room temperature and
±
1.4%
overall accuracy over temperature, line and load regulations.
The dropout voltage of the ADP3303A is only 150 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 heat sink
or large copper surface on the PC board. This keeps PC board
real estate to a minimum and makes the ADP3303A very attrac-
tive for use in portable equipment.
The ADP3303A 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 ADP3303A is characterized by having the output voltage
divider placed externally. The output voltage can be adjusted
from 2.2 V to 10 V.
