POWER MANAGEMENT  
CIRCUIT FOR  
PORTABLE DEVICES  
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 where noise is an  
important feature. Outputs deliver 40µVRMS typical (10–100kHz) at nominal  
output current.  
SILICON MONOLITHIC  
INTEGRATED CIRCUIT  
With a 50dB ripple rejection under 10kHz, the circuit naturally shields the  
downstream electronics against DC choppy lines. This parameter  
guarantees a clean operation for battery operated devices.  
Finally, housed in a compact Thin Quad Flat Pack TQFP–32 package, the  
MC33283 gathers all the features necessary to power future portable radios.
