ADP3303
–3–
REV.
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 ADP3303 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.
PIN FUNCTION DESCRIPTIONS
Pin Mnemonic Function
1 & 2 OUT Output of the Regulator. Bypass to
ground with a 0.47 µF or larger
capacitor. Pins 1 and 2 must be con-
nected together for proper operation.
3 NR Noise Reduction Pin. Used for reduc-
tion of the output noise. (See text for
details.) No connection if not used.
4 GND Ground Pin.
5 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.
6 ERR Open Collector Output. Goes low to
indicate that the output is about to go
out of regulation.
7 & 8 IN Regulator Input. Pins 7 and 8 must
be connected together for proper
operation.
