12V to 4.5V, 6V & 9V Converter

We often feel the requirements of12v to 4.5V, 6V, 9V converter circuit when we have 12v battries forexample car battery or any other 12v battery. We have lots ofelectronics which runs from different voltages like 4.5V, 6V, 9V etcand we can run them with our 12v batteries by usingconverter circuit.So here is the simple circuit which will do a great job for thispurpose.The chart below the circuit is mentioned to obtain the desiredvoltage by changing the components values.
