Re: Voltage Regulators
Voltage regulators (DC-DC converter) are classified as either linear regulators or switching regulators.
Linear regulators is used to described an electronic regulator in which the voltage or current is controlled using transistors or other active devices as variable impedance elements. This type of regulator is called the linear regulator because the transistor (BJT) operates in the linear region, rather than in the saturation or cutoff region. In MOS transistor, it operates in saturation (pin-off) region, but the regulator is still known as a linear regulator.
Switching regulators, in contrast to linear regulators, use the transistors as switches that are either “on” or “off”, with the current or voltage controlled by pulse-width modulation or other modulation method.
LDO --> one kinds of linear regulator
