I need to design a voltage regulator circuit to provide a constant voltage of 5V to a load from a variable supply voltage. The load current carries from 0 to 100 mA and the source voltage varies from 8 to 10 V. You may assume that ideal Zener diodes are available. Resistors of any value can be specified. Draw a diagram and specify the value of each component. Find the worse case (maximum) power dissipated in each component of your regulator. I'm completely lost and I have very little time to finish this. Thanks in advance for any help that you can give.
