... 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 ADP3605 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges larger than 600 V HBM. ...

... A small 1 F input bypass capacitor, preferably with low ESR, such as tantalum or multilayer ceramic, is recommended to reduce noise and supply transients and supply part of the peak input current drawn by the ADP3605. A large capacitor is rec- ommended if the input supply is connected to the ADP3605 through long leads the pulse current drawn by the device might affect other circuitry through supply coupling ...

... This is far below the 660 mW power dissipation capability of the ADP3605 in SO-8 or 600 mW in RU-14 General Board Layout Guidelines Since the ADP3605’s internal switches turn on and off very fast, ADP3605-3 good PC board layout practices are critical to ensure optimal operation of the device. Improper layouts will result in poor load regulation, especially under heavy loads ...

... LOAD CURRENT – mA Figure 15. Maximum Unregulated Output Voltage Regulated Adjustable Output Voltage For the adjustable version of the ADP3605, the regulated out- put voltage is programmed by a resistor which is inserted be- tween the V and V pins, as illustrated in Figure 16. SENSE OUT The inherent limit of the output voltage of a single inverting charge pump stage is – ...
