Versatile 6 Regulator Power
Management Circuit for
Cellular Subscriber
Terminal
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.
specification makes the circuit an ideal candidate where noise is an
important feature. Outputs deliver 40mVRMS typical (10−100kHz) at
nominal output current.
the downstream electronics against DC choppy lines. This parameter
guarantees a clean operation for battery operated devices.
the MC33283 gathers all the features necessary to power future portable
