If you've got the right
voltage zener diode and a power transistor,
you can make your own fixed
voltage regulator using the circuit diagram above. The output
voltage will be 0.6 volts below the diode's zener
voltage, due to the base-emitter
voltage drop across the transistor.

A simple voltage/current regulator can be made from a resistor in series with a diode (or series of diodes). Due to the logarithmic shape of diode V-I curves, the voltage across the diode changes only slightly due to changes in current drawn or changes in the input.
