GND
Output of Regulator 1, fixed 3.0 V, 3.2 V,
3.3 V or 5 V output voltage. Sources up to
200 mA. Bypass to ground with a 0.47 µF
capacitor.

Regulator Input. Supply voltage can range
from ϩ3.0 V to ϩ12 V. Pins 5 and 8 must be
connected together for proper operation.
Active Low Shutdown Pin for Regulator 2.
Connect to ground to disable the Out 2 out-

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 ADP3302 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.
