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, twoway 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 40mVRMS typical (10100kHz) at
nominal output current.
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 TQFP32 package,
the MC33283 gathers all the features necessary to power future portable
radios.
Features:
6 regulated outputs:
2.85V, four outputs: 10135mA
4.75V @ 15mA
5.0V @ 20mA
Lownoise: 40μVRMS at nominal output levels (10Hz100kHz)
Ultralow reverse current in OFF mode (200nA typical)
Twomode regulator: output 5 switches from 3 to 5V with SEL pin
activated
Thermal shutdown for a rugged and reliable operation
All outputs are shortcircuit proof
Applications:
All Portable radios (GSM etc.)
Bursting systems (TDMA etc.)
Battery operated devices
