MOSFET - Wikipedia
In electronics, the metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, MOS FET, or MOS transistor) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device.
Difference between Mosfet and Voltage Regulator? - Electrical ...
Jul 24, 2010 · In very basic terms, a voltage regulator is a device for building a power supply, whereas a mosfet is something you use to build an amplifier. A voltage regulator is basically an integrated circuit that has several transistors within it, while a mosfet is exactly a single transistor.
Understanding How a Voltage Regulator Works | Analog Devices
Aug 1, 2009 · A linear regulator employs an active (BJT or MOSFET) pass device (series or shunt) controlled by a high gain differential amplifier. It compares the output voltage with a precise reference voltage and adjusts the pass device to maintain a constant output voltage.

A guide to using FETs for voltage controlled circuits, Part 1
Oct 13, 2017 · The answer is yes (e.g., VCR11), but it turns out that virtually any other FET (e.g., JFET and MOSFET) can be used as a voltage controlled resistor. Basic voltage controlled resistor (VCR) circuits One of the simplest uses of a voltage controlled resistor is an electronically controlled attenuator or “volume control”.
Voltage Regulator Types and Working Principle | Article | MPS
A voltage regulator is a circuit that creates and maintains a fixed output voltage, irrespective of changes to the input voltage or load conditions. Voltage regulators (VRs) keep the voltages from a power supply within a range that is compatible with the other electrical components.
