The ADP3605 is a 120 mA regulated output, switched capacitor
voltage inverter. It provides a regulated output voltage with
minimum voltage loss and requires a minimum number of

internal oscillator of the ADP3605 runs at a 500 kHz nominal
frequency that produces an output switching frequency of
250 kHz. This allows for the use of smaller charge pump and

The ADP3605 provides an accuracy of ±3% with a typical
shutdown current of 2 μA. It can also operate from a single
positive input voltage as low as 3 V. The ADP3605 is adjustable
via external resistors over a ?3 V to ?6 V range.
*FOR BEST PERFORMANCE, 10μF IS RECOMMENDED
