  2. LM317 - Wikipedia

    en.wikipedia.org/wiki/LM317

    As linear regulators, the LM317 and LM337 are used in DC to DC converter applications. Linear regulators inherently waste power; the power dissipated is the current passed multiplied by the voltage difference between input and output. A LM317 commonly requires a heat sink to prevent the operating temperature from rising too high. For large ...

    English: Schematic of a 1A current regulator using LM317 adjustable voltage regulator. The open-circuit voltage assumes the output stage of the LM317 saturates at approximately 0.2 V and the adjust pin sinks enough current so that the voltage drop across the 1.25 ohm resistor is 1.25 V, which corresponds to the approximate temperature-compensated bandgap of silicon.

  6. Voltage regulator - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulator

    The power supply is designed to only supply a maximum amount of current that is within the safe operating capability of the shunt regulating device. If the stabilizer must provide more power, the shunt output is only used to provide the standard voltage reference for the electronic device, known as the voltage stabilizer.

  7. Regulated power supply - Wikipedia

    en.wikipedia.org/wiki/Regulated_power_supply

    A regulated power supply is an embedded circuit; it converts unregulated AC (alternating current) into a constant DC. With the help of a rectifier it converts AC supply into DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.

  9. Bandgap voltage reference - Wikipedia

    en.wikipedia.org/wiki/Bandgap_voltage_reference

    Moreover, this type of circuit might consume a lot of power to reach to the desired noise and precision specification. [ 12 ] Despite these limitations, the band gap voltage reference is widely used in voltage regulators, covering the majority of 78xx, 79xx devices along with the TL431 and the complementary LM317 and LM337.
