In electronic devices, a linear regulator creates the necessary voltage for subsequent systems mainly from the power supplied by the battery. A linear regulator can output a lower steady voltage from the input voltage.
A linear regulator employs an active (BJT or MOSFET) pass device (series or shunt) controlled by a high gain differential amplifier. It compares the output voltage with a precise reference voltage and adjusts the pass device to maintain a constant output voltage.
Linear regulators are simpler regulators that step down the input voltage. The goal is to set the output to a specific DC voltage. Switching regulators provide much higher efficiencies, but they can be more complex and create switching noise.
