1. DESCRIPTION

The ADP3605ARZ-R7 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 external components. In addition, the ADP3605 does not require the use of an inductor. Pin-for-pin and functionally compatible with the ADP3604, the 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 filter capacitors. 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.
