High Current Adjustable LM317 Power Supply Circuit
In this post IC LM317 is chip for controlling voltage but it give only 1.5 amp current. We can add one more part called TIP35 transistor with LM317. When LM317 tell it and this transistor act like a follower. Now with this transistor LM317 can handle big current up to 10 amp. This article for […]
Simple Current Limiter Circuit using Transistors
To begin with, this Simple Current Limiter Circuit using Transistors gives tutorial to show how to make a circuit that stop giving too much power to other electronics. Also, it helps to protect from overload by using two transistors and one special resistor. What is a Current Limiter Circuit using Transistors: A transistor current limiter […]
Simple Voltage Regulator Circuit using Transistor and Zener
This Simple Voltage Regulator Circuit using Transistor and Zener work like bodyguard for electricity, because it uses one transistor like door keeper and one special Zener diode to keep voltage not going up-down. Furthermore, the Zener diode gives fixed voltage and transistor follow that voltage to keep same for our device. Also, this project is […]
