CXLD64277 is a dual-channel low dropout regulator supplying up to 200mA at each channel. The output voltages are selectable between 2.8V/3.3V for Channel-1 and 1.3V/1.8V for Channel-2 with 3% accuracy. The CXLD64277 uses internal PMOS transistors as the pass devices to regulate the output voltages. The IC consumes 120μA supply current when both channels are turned on, and is nearly independent of load currents and dropout conditions. The EN1 and EN2 pins allows for individual channel controls. When both outputs are shut down simultaneously, the chip will be turned off and consumes nearly zero operating current which is suitable for battery-power devices. Other features include a current limiting, and over temperature protection.
