DC 12V to DC 6V-7.5V-9V Converter using 2N3055
This circuit is DC to DC converter model step down voltage. That can modify voltage input 12V DC from be DC 6V , 7.5V and 9V by have the size current about 1A – 2 Amp think. Be easy circuit use Zener diode maintain one’s position voltage. Be stable and have transistor 2N3055. When you several examples of the output voltage 6Vout, R1 =330 , ZD1=6.6V ; 7.5Vout, R1 = 270 , ZD1 = 8.2V ; 9Vout , R1=180 , ZD1=10V ; Perform enlarge the trend tallly go up fully be usable next , see the detail in the circuit and read to add

5 Volt Linear power supply regulator using 2N3055
This is 5 Volt Linear power supply regulator circuit. It uses electronics part that seek easily have no zener diode , and the integrated circuit use Transistor 2N3055 and other. Which seek easily use diode perform heal voltage be stable. By diode 1N914 number uses 1N4148 number can replace. For Transistor 2N3417 use the number BD139 equiv get. If use Transformer 1-2A circuit be this size give current get about 1 Amp. Friends may don’t be bored with line this circuit. I thinks it may advantage seek part easy and economize good yes.
