GENERAL DESCRIPTION
The ADP3303A is a member of the ADP330x family of preci-
sion low dropout anyCAP voltage regulators. The ADP3303A
stands out from conventional LDOs with a novel architecture,
an enhanced process and a new package. Its patented design
requires only a 1
μ
F output capacitor for stability. This device is
insensitive to output capacitor ESR (Equivalent Series Resis-
tance), and is stable with any good quality capacitor, including
ceramic types (MLCC) for space restricted applications. The
ADP3303A achieves exceptional accuracy of
±
0.8% at room
temperature and
±
1.4% overall accuracy over temperature, line
and load variations. 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 an 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
attractive for use in portable equipment.
The ADP3303A operates over an input voltage range of 3.2 V
to 12 V and delivers a load current in excess of 200 mA. The
output voltage can be adjusted from 2.2 V to 10 V using an
external resistor divider. It also 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 fea-
tures include shutdown and optional noise reduction capabilities.
