Regulator Input.
Ground Pin.
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.

ERR/NC Open Collector. Output that goes low
to indicate the output is about to go
out of regulation. This pin can be left open.
(NC = No Connect).
*This is a stress rating only; operation beyond these limits can cause the device to
be permanently damaged.
OUT
Output of the Regulator, fixed 2.7, 2.85,
2.9, 3.0, 3.3 or 3.6 volts output voltage.
Bypass to ground with a 0.47 µF or larger
capacitor.

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 ADP3309 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.
