Linear voltage regulators are used to maintaining a steady output voltage. They are step-down converters where the input voltage is always higher than the output voltage. The output voltage can be adjusted by external resistors. 78xx series is a very popular linear voltage regulator series. 78xx series, however, do not require external components for setting […]
