![]() At 1A the current.ĭo you know which transistor has the most heat loss? Or… It must dissipate or reduce it.ĭo you see an image? It is simple. The transistor-Q1 works look like a resistor. In this series pass transistor regulator. Of course, energy will be expressed by heat. ![]() It should reduce the loss of energy in the circuit to a minimum. ![]() The transistor- 2N3055 can power load current up to 2A. The circuit will induct them into the transient noise. The power supply has a stray magnetic field. R1 increases the stability of the load circuit.C3 is a 0.047uF decoupler capacitor to filter out the transient noise.C2 keeps the reference voltage to be stable better. ![]() C1 is a smoothing capacitor at an input.Thus, it has a much more stabilized output. The advantage of this circuit, we can use a tiny current to Zener diode and base of a transistor. Because the voltage of Base-emitter less, transistor Q1 works less too. So it keeps the output voltage to be a constant level. But the base-emitter voltage rises up, transistor Q1 works more. In general, the output voltage is low down. In the circuit, the transistor has a proper gain and changing of VBE help it. ![]() Since it is a power supply that regulates a certain power output. This voltage is still suitable for many loads using the 12V supply such as receiver radios. ![]()
