PIN FUNCTION DESCRIPTIONS
Pin
No. Mnemonic Function
1, 2, 3 OUT Output of the Regulator. Bypass to
ground with a 1.0 µF or larger capacitor.
All pins must be connected together for
proper operation.
4 GND Ground Pin.
5 FB Feedback Input. Connect to an external
resistor divider which sets the output
voltage. Can also be used for further
reduction of output noise (see text for
detail).
Capacitor required if C
OUT
> 3.3 µF.
6 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.
7, 8 IN Regulator Input. All pins must be con-
nected 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 ADP3336 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.
