  2. LM317 - Wikipedia

    en.wikipedia.org/wiki/LM317

    LM317 with heat sink. 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.

  4. 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.

    The general negative feedback arrangement can be implemented by an IC voltage regulator (LM317 voltage regulator on Figure 8). As with the bare emitter follower and the precise op-amp follower above, it keeps up a constant voltage drop (1.25 V) across a constant resistor (1.25 Ω); so, a constant current (1 A) flows through the resistor and the ...

  7. TO-220 - Wikipedia

    en.wikipedia.org/wiki/TO-220

    The TO-220 package is a "power package" intended for power semiconductors and an example of a through-hole design rather than a surface-mount technology type of package. TO-220 packages can be mounted to a heat sink to dissipate several watts of waste heat.

  8. 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.
