onsemi MC33283
The MC33283 is a complete power management solution for portable devices such as telephone handsets, two−way radios, etc. With a 50dB ripple rejection under 10kHz, the circuit naturally shields the downstream electronics against DC choppy lines. Finally, housed in a compact Thin Quad Flat Pack TQFP−32 package, the MC33283 gathers all the features necessary to power future portable radios.| Part No. | MC33283 |
