... Post Regulator for Switching Supplies Bar Code Scanners GENERAL DESCRIPTION The ADP3301 is a member of the ADP330x family of precision low dropout anyCAP™* voltage regulators. The ADP3301 stands out from the conventional LDOs with a novel architec- ture, an enhanced process and a new package. Its patented design includes a noninverting wideband driver and a stage that permits the use of an internal “ ...

... 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 ADP3301 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 ...

... Capacitor Selection Output Capacitors: as with any micropower device, output transient response is a function of the output capacitance. The ADP3301 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. However, larger capacitors can be used if high output current surges are anticipated ...
