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.

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.
