ADP3303

–3–

REV. A

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

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.
