TYPICAL CIRCUIT
The CE Pin is only avaiable with the XC6705
GREEN OPERATION (GO)
The GO (Green Operation) function of the XC6705/06 series enables a low quiescent current of 1.2μA with 50dB high power supply ripple rejection.
The supply current of the LDO will rise and fall as the output current demand changes. When the output load rises, the responsiveness of the internal error amplifier improves which increases the LDO performance and as the output load decreases the responsiveness of the error amplifier reduces and supply current falls, as shown in the graph.
As a result, both low current consumption at light load and high-speed response at heavy load are achieved
