MC33283 Versatile 6 Regulator Power Management Circuit for Cellular Subscriber Terminal The MC33283 is a complete power management solution for portable devices such as telephone handsets, two way radios, etc. Thanks to its large scale integration, the device offers up to seven Low DropOut regulators (LDO), two of them delivering a voltage higher than the battery’s. Despite the presence of an internal charge pump, the overall noise specification makes the circuit an ideal candidate wher.
