  2. 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.

    7805 in TO-220 and TO-92 packages Internal die of a Tesla MA7805. 78xx (sometimes L78xx, LM78xx, MC78xx...) is a family of self-contained fixed linear voltage regulator integrated circuits.

  6. IC power-supply pin - Wikipedia

    en.wikipedia.org/wiki/IC_power-supply_pin

    In circuit diagrams and circuit analysis, there are long-standing conventions regarding the naming of voltages, currents, and some components. [5] In the analysis of a bipolar junction transistor, for example, in a common-emitter configuration, the DC voltage at the collector, emitter, and base (with respect to ground) may be written as V C , V ...

    en.wikipedia.org/wiki/555_timer_IC

    Silicon die of the first 555 chip (1971) Die of a CMOS NXP ICM7555 chip The timer IC was designed in 1971 by Hans Camenzind under contract to Signetics. [3] In 1968, he was hired by Signetics to develop a phase-locked loop (PLL) IC.

  8. Voltage regulator - Wikipedia

    en.wikipedia.org/wiki/Voltage_regulator

    Mirror-image insertion protection means that a regulator is designed for use when a voltage, usually not higher than the maximum input voltage of the regulator, is applied to its output pin while its input terminal is at a low voltage, volt-free or grounded. Some regulators can continuously withstand this situation.
