The transistor (or other device) is used as one half of a voltage divider to establish the regulated output voltage. The output voltage is compared to a reference voltage to produce a control signal to the transistor which will drive its gate or base. With negative feedback and good choice of compensation, the output voltage is kept reasonably constant. Linear regulators are often inefficient: since the transistor is acting like a resistor, it will waste electrical energy by convertin… Linear voltage regulators—also called LDOs or low-dropout linear regulators—use a transistor controlled by a negative-feedbackcircuit to produce a specified output voltage that remains stable despite variations in load current and input voltage.
