GENERAL DESCRIPTION
The ADP3300 is a member of the ADP330x family of precision
low dropout anyCAP™ voltage regulators. The ADP3300
stands out from conventional LDOs with a novel architecture
and an enhanced process. Its patented design requires only a
0.47 µF output capacitor for stability. This device is stable with
any capacitor, regardless of its ESR (Equivalent Series Resistance)
value, including ceramic types (MLCC) for space restricted appli-
cations. The ADP3300 achieves exceptional accuracy of ±0.8%
at room temperature and ± 1.4% overall accuracy over tempera-
ture, line and load regulations. The dropout voltage of the
ADP3300 is only 80 mV (typical) at 50 mA.
The ADP3300 operates with a wide input voltage range from
3.0 V to 12 V and delivers a load current in excess of 50 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™
anyCAP is a registered trademark of Analog Devices Inc.
LDO family offers a wide range of output voltages and output
current levels from 50 mA to 200 mA:
ADP3301 (100 mA)
ADP3302 (100 mA, Dual Output)
ADP3303 (200 mA)

PIN FUNCTION DESCRIPTIONS
Pin Mnemonic Function
1 GND Ground Pin.
2 NR Noise Reduction Pin. Used for further
reduction of the output noise (see text for
details). No connection if not used.
3 SD Active Low Shutdown Pin. Connect to
ground to disable the regulator output.
When shutdown is not used, this pin should
be connected to the input pin.
4 OUT Output of the Regulator, fixed 2.7, 3.0, 3.2,
3.3 or 5 volts output voltage. Bypass to
ground with a 0.47 µF or larger capacitor.
5 IN Regulator Input.
6 ERR Open Collector Output which goes low to
indicate that the output is about to go out
of regulation.

ORDERING GUIDE
WARNING!
ESD SENSITIVE DEVICE
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the ADP3300 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
