Products/Services for Rp AVR Automatic Voltage Regulators

  • Voltage Regulators-Image
    Voltage Regulators - (176 companies)
    Voltage regulators are power converters that provide voltage control capabilities. They accept a voltage that varies over a given range and generate an output voltage that does not vary. Unlike integrated circuit (IC) voltage regulators and IC...

  • IC Voltage Regulators-Image
    IC Voltage Regulators - (305 companies)
    IC voltage regulators are three-terminal devices that provide a constant DC output voltage that is independent of the input voltage, output load current, and temperature. IC voltage regulators are used in power supplies that hold their output...
  • IC Linear Voltage Regulators-Image
    IC Linear Voltage Regulators - (133 companies)
    Integrated circuit (IC) linear voltage regulators use voltage-controlled sources to force a fixed voltage to appear at their output terminal. Integrated circuit (IC) linear voltage regulators use an active pass element to reduce the input voltage...
  • IC Switching Voltage Regulators-Image
    IC Switching Voltage Regulators - (106 companies)
    IC switching voltage regulators are integrated circuits (ICs) that store energy in an inductor, transformer, or capacitor and then use this storage device to transfer energy from the input to the output in discrete packets over a low-resistance...
  • Pressure Regulators-Image
    Pressure Regulators - (1188 companies)
    Pressure regulators are used to maintain a constant outlet pressure or flow. Pressure regulators are used to reduce the pressure in a system to a lower pressure or to regulate system pressure at the desired value. Among the types of pressure...
    Gas Pressure Regulators - (279 companies)
    Gas pressure regulators reduce the pressure of a gas, as it passes through a cylinder or process line, to another piece of equipment. Regulators are not flow control devices. They are used to control delivery pressure only. Gas pressure regulators...
    Air Pressure Regulators - (380 companies)
    Air pressure regulators control pressure in air lines (usually adjustable) to remove fluctuations and maintain consistent pressure for pneumatic devices. Air pressure regulators control the pressure in air lines used by pneumatic tools and machines...
    Charge Pump Regulators - (27 companies)
    Charge pump regulators are circuits that generate higher voltages from low voltage inputs by using capacitors as storage elements. They are used in notebook computers and mobile phones. Charge pump regulators are circuits that generate higher...
    Automatic Identification Systems (AIS) - (47 companies)
    Automatic identification systems (AISs) transmits location data about a vessel to other ships and coastal facilities. An AIS is required on large vessels, tankers, and some ships that operate in congested waters. Automatic identification systems...
    Voltage Dividers and Voltage References - (64 companies)
    Voltage dividers and voltage references provide highly-accurate reference voltages for calibration and testing purposes. Voltage dividers produce an output voltage (Vout) that is proportional to an input voltage (Vin). They consist of a series...
