NOTES
1
Ambient temperature of +85
°
C corresponds to a junction temperature of +125
°
C under typical full load test conditions.
2
Application stable with no load.
3
Assumes the use of ideal resistors. Overall accuracy also depends on the tolerance of the external resistors used to set the output voltage.
Specifications subject to change without notice.

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!

Function
Output of the Regulator. Bypass to ground
with a 0.47
μ
F 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.
