This circuit is a circuit diagram rgulator voltage. Many times we need a different voltage from 12V battery. With the circuit, we can take a voltage smaller or larger, positive or negative, from the 12V battery. The idea of this diagram circuits based on the oscillator 7KHZ rough around the R1, C28, which leads the rest IC1 74HC14 gates, which are connected in parallel, (so that they provide an essential flow of the drive), that drives them to the line transistor Q1 to Q4. Then there are two series of “cascade” is formed from diodes and capacitors, D1 through D4, C14 to C17 to the negative and D5 to D9, C23 to C19 to the positive voltage, which encourages the appropriate stabilizer. In the output of the stabilizer is the inductor, which they remove and the last remnants of oscillation. Currently we can take the output sequence 100 to 200 mA. The following is a schematic drawing:

The total time that will give the current battery capacity that we want, it’s up to the capacity Ah, for more and more time. All transistors and stabilizer, whether it is they are placed in a heatsink, to remove the heat it generated.
