... 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 ...

... APPLICATION INFORMATION Capacitor Selection Output Capacitor: The stability and transient response of the LDO is a function of the output capacitor. The ADP3331 is stable with a wide range of capacitor values, types, and ESR (anyCAP). A capacitor as low as 0. all that is needed for stability; larger capacitors can be used if high current surges on the output are anticipated. The ADP3331 is stable with extremely low ESR capacitors (ESR ª ...

... OFF Figure 3. Noise Reduction Circuit Output Voltage The ADP3331 has an adjustable output voltage that can be set by an external resistor divider. The output voltage will be divided by R1 and R2, and then fed back to the FB pin. Refer to Figure 3. For the output voltage to have the lowest possible sensitivity to ...
