ADP3334

–3–

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 ADP3334 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.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only. Functional operation of the

device at these or any other conditions above those listed in the operational

sections of this specification is not implied. Exposure to absolute maximum rating

conditions for extended periods may affect device reliability.

Mnemonic

Function

GND

Ground Pin.

SD

Shutdown Control. Pulling this pin low

turns on the regulator.

IN

Regulator Input.

OUT

Output. Bypass to ground with a 1.0 µF or

larger capacitor.

FB

Feedback Input. FB should be connected to

an external resistor divider that sets the

output voltage.

NC

No Connection.
