... 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 ADP3607 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 ...

... 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 ADP3607. A large capacitor is rec- ommended if the input supply is connected to the ADP3607 through long leads the pulse current drawn by the device might affect other circuitry through supply coupling ...

... To avoid excessive noise pickup, keep the V line as short as possible and away from any noisy line. Shutdown Mode The ADP3607’s output can be disabled by pulling the SD Pin to a TTL /CMOS logic high level which will stop the internal oscillator. Applying a logic low will turn ON the oscillator. If the shutdown feature is not used, the SD pin should be tied to ground ...

... ADP3607 Regulated Adjustable Output Voltage For the adjustable version of the ADP3607, the regulated out- put voltage is programmed by a resistor that is inserted between the V and V pins, as illustrated in Figure 19. The in- SENSE OUT herent limit of the output voltage of a single doubling charge pump stage is two times the input voltage. The scaling factor of 2 ...
