    Hi guys , my teacher asked me to design a power conditioning unit like below.

    Power conditioning block diagram( Circuit Schematics are not mandatory, but as a result it will be evaluated as bonus point)
    Description: Input Voltage: 28VDC
    Output Voltage: according to 5 VDC, (Isolated) (10 points)
    according to 3,3 VDC, (Isolated) (10 points)
    according to 28 VDC (Isolated) (10 points)

    I choosed 2 regulators from Digikey for 3V3 and 5V output . But i guess , i must use 28V directly without regulator for 28V output? Or can i use 28V input voltage with some capacitors to eliminate noise . My last question , are they enough for power conditioning unit or something else is required and what does isolated stand for ? No other information about the question is given .

    Isolated means that there is no DC connection between the output and the input or any of the other outputs.
