PIN FUNCTION DESCRIPTIONS
Function
Output of the Regulator. Bypass to ground with a 1.0 µF or larger capacitor. All pins must be
connected together for proper operation.
Supply Voltage
Ground Pin
Power Good. Used to indicate output is in regulation.
Active Low Shutdown Pin. Connect to ground to disable the regulator output. When shut down
is not used, this pin should be connected to the input pin.
Regulator Input. All pins must be connected together for proper operation.
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 ADP3342 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.
