The smaller the value of the variable resistor, the smoother the adjustment. Depending on the type of transistor, the switching circuit also changes. When the resistance changes, the output voltage is regulated. And if the output moves to the upper position, then the transistor becomes maximally open, and the output signal level will be equal to the voltage of the power source minus the drop in the potential difference across the transistor. If the control terminal of the resistor is in the lower position, then the voltage at the output of the circuit is zero. The operation of the circuit is simple: with the help of a variable resistor, induction (unlocking of the transistor) occurs. All you need is a transistor and a variable resistor. To control the output voltage for low-power devices, you can assemble a simple voltage regulator into 2 parts. Only two components are required for the voltage regulator circuit transistor and variable resistor. It is the simplest circuit.Ĭomponents Required for Voltage Regulator Circuits using Transistor Voltage Regulator Circuits using Transistor Circuit DiagramĪ circuit diagram of a simple voltage regulator circuit is given below.
