Pin number 1 is the input pin, Pin 2 is the ground pin, Pin 3 is the output pin when seen as printed area facing the person. A 12v to 6v dc converter can be made with a popular IC LM voltage regulator as this IC gives adjustable output DC voltage with some changes in the external circuit.
It is useful for medium to high current circuits 1 Ampere to 1. Generally, LM is found at variable power supply circuits that give regulated voltage 1. A heat-sink is required to cooling the IC from the heat generated also prevents it from damaging. Components required: A 12v power supply, a 1.
This the formula for the output voltage of 12v to 6v reducer using LM It gives an approximately required output when R2 and R1 are chosen to equate the formula.
Consider the value of resistors in kilo-ohms so as to reduce power consumption. Also, check the 12v to 6v regulator using the transistor below, this circuit is almost obsolete as there is various single package IC available to buy and use. A very convenient and compact circuit can be implemented with modern solutions.
The schematic below shown below is the 12v to 6v reducer for a small current drawing circuit , or to take reference voltage in comparator circuit or circuit for indicator LED.
You can drive few LEDs in series across the resistor R2 1. You can take the output from resistor R1. This type of circuit is not that popular among the makers because of low current, thus not recommended for use in projects. We can response you via email,mobile phone and others.
