Monolithic 600mA Step-Down Regulator with Low Quiescent Current

The ISL8010 is a synchronous, integrated FET 600mA step-down regulator with internal compensation. It operates with an input voltage range from 2.5V to 5.5V, which accommodates supplies of 3.3V, 5V, or a Li-Ion battery source. The output can be externally set from 0.8V to VIN with a resistive divider.
