    en.wikipedia.org/wiki/LM317

    The LM317 is an adjustable positive linear voltage regulator. It was designed by Bob Dobkin in 1976 while he worked at National Semiconductor. [1] The LM337 is the negative complement to the LM317, which regulates voltages below a reference. It was designed by Bob Pease, who also worked for National Semiconductor. [1]

  5. 78xx - Wikipedia

    en.wikipedia.org/wiki/78xx

    As they are based on a linear regulator design, the input current required is always the same as the output current. As the input voltage must always be higher than the output voltage, this means that the total power (voltage multiplied by current) going into the 78xx will be more than the output power provided. The difference is dissipated as ...

  6. Voltage-regulator tube - Wikipedia

    en.wikipedia.org/wiki/Voltage-regulator_tube

    The unregulated supply voltage must be 15–20% above the nominal output voltage to ensure that the discharge starts; The output can be higher than nominal if the current through the tube is too low. When sufficient voltage is applied across the electrodes, the gas ionizes, forming a glow discharge around the cathode electrode.

  7. Voltage regulator - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulator

    An integrated circuit voltage regulator. A voltage regulator is a system designed to automatically maintain a constant voltage. It may use a simple feed-forward design or may include negative feedback. It may use an electromechanical mechanism, or electronic components. Depending on the design, it may be used to regulate one or more AC or DC ...

  8. Regulated power supply - Wikipedia

    en.wikipedia.org/wiki/Regulated_power_supply

    Modern regulated supplies mostly use a transformer, silicon diode bridge rectifier, reservoir capacitor and voltage regulator IC. There are variations on this theme, such as supplies with multiple voltage lines, variable regulators, power control lines, discrete circuits and so on. Switched mode regulator supplies also include an inductor.

  9. Switched-mode power supply - Wikipedia

    en.wikipedia.org/wiki/Switched-mode_power_supply

    Stand-alone switched-mode power supply An adjustable switched-mode power supply for laboratory use. A switched-mode power supply (SMPS), also called switching-mode power supply, switch-mode power supply, switched power supply, or simply switcher, is an electronic power supply that incorporates a switching regulator to convert electrical power efficiently.
