NOTES

1Ambient temperature of 85∞C corresponds to a junction temperature of 125∞C under typical full load test conditions.

2Application stable with no load.

3Assumes the use of ideal resistors. Overall accuracy also depends on the tolerance of the external resistors used to set the output voltage.

Function

Output of the Regulator. Bypass to ground

with a 0.47 mF or larger capacitor.

Regulator Input.

Open Collector Output that goes low to

indicate that the output is about to go out

of regulation.

Ground.

Feedback Input. Connect to an external

resistor divider, which sets the output

voltage.

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.

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 ADP3331 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.

WARNING!
