... 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 ADP3330 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 ...

... THEORY OF OPERATION The new anyCAP LDO ADP3330 uses a single control loop for regulation and reference functions. The output voltage is sensed by a resistive voltage divider consisting of R1 and R2 which is varied to provide the available output voltage options. Feedback is taken from this network by way of a series diode (D1) and a second resistor divider (R3 and R4) to the input of an amplifier ...

... Capacitor Selection Output Capacitors: as with any micropower device, output transient response is a function of the output capacitance. The ADP3330 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 output current surges are anticipated ...

... ADP3330 draws 34 A typical under light load situations (i.e., load current = 100 A), which results in low power consumption when the cell phone is in standby mode. Figure 23 shows an application in which the ADP3330 is used in a handset to provide 2.75 V nominal output voltage. The cell phone is powered from 3 cell NiCd or 1 cell Li-Ion battery. ...

... ADP3330 APPLICATION CIRCUITS Crossover Switch The circuit in Figure 24 shows how two ADP3330s can be used to form a mixed supply voltage system. The output switches between two different levels selected by an external digital input. Output voltages can be any combination of voltages from the Ordering Guide of the data sheet. ...
