GENERAL DESCRIPTION

The ADP3307 is a member of the ADP330x family of precision
low dropout anyCAP voltage regulators. The ADP3307 stands
out from the 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 type
of capacitor regardless of its ESR (Equivalent Series Resistance)
value, including ceramic types (MLCC) for space restricted
applications. The ADP3307 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 ADP3307 is only 120 mV (typical) at 100 mA.

The ADP3307 operates with a wide input voltage range from

3.0 V to 12 V and delivers a load current in excess of 100 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 from 50 mA to 300 mA:

ADP3300 (50 mA, SOT-23-6)
ADP3307 (100 mA, SOT-23-6)
ADP3301 (100 mA, R-8)
ADP3302 (100 mA, Dual Output)
ADP3303 (200 mA)

Pin Name Function

1 GND Ground Pin
2 NR Noise Reduction Pin. Used for further reduc-

tion 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 V, 3.0 V,

3.2 V or 3.3 V output voltage. Bypass to
ground with a 0.47 µF or larger capacitor.

5 IN Regulator Input
6 ERR Open Collector Output that goes low to indi-

cate that the output is about to go out of
regulation.

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 ADP3307 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.
