V
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 ex-  
ternal 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 500 kHz nominal  
frequency which 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 shut-  
down current of 2 µA. It can also operate from a single positive  
input voltage as low as 3 V. The ADP3605 is offered with the  
regulation fixed at –3 V or adjustable via external resistors over  
a –3 V to –6 V range.
