A voltage regulator will contain some kind of voltage reference to set the output voltage. A typical application for a voltage regulator will be to accept a 9V unregulated input from a wall-mount power supply and produce a 5V or 3.3V output to power anything from a desktop clock to a printer.
Many circuits will need a voltage regulator between the power supply and the electronics. In this article, Stuart breaks down the two broad types of voltage regulators: linear and switching. Avoltage regulator is a device that produces a constant output voltage to power an electronic circuit.
In this article, Stuart breaks down the two broad types of voltage regulators: linear and switching. Avoltage regulator is a device that produces a constant output voltage to power an electronic circuit. This is different from a voltage reference, which produces a constant voltage as a reference for some measurement device.
If you have a desktop or laptop PC, it likely has multiple voltage regulators on the main board. Voltage regulators fall broadly into two types: linear and switching. A linear regulator is always a step-down device, regulating a higher voltage to a lower voltage of the same polarity.
This is different from a voltage reference, which produces a constant voltage as a reference for some measurement device. Functionally, the difference is that a voltage regulator sources current to whatever it is supplying, while a voltage reference may be passive (sourcing no current) or else it may source very small currents.
A linear regulator is always a step-down device, regulating a higher voltage to a lower voltage of the same polarity. For example, a positive regulator may produce a fixed 5V output from an unregulated 12V input. A switching regulator uses switching techniques to produce a regulated output voltage.
Zener Diode as Voltage Regulator Tutorial
The zener voltage regulator consists of a current limiting resistor R S connected in series with the input voltage V S with the zener diode connected in parallel with the load R L in this reverse biased condition. The stabilised output voltage is always selected to be the same as the breakdown voltage V Z of the diode. Tutorial Example No1

The Car Voltage Regulator (How It Works + How To Test It)
If the voltage output drops below 13.5V, the power supply is low so the regulator''s sensors close the circuit to the alternator. This causes the alternator to switch on, increasing the magnetic field and delivering power to the battery. Then, once the voltage output in the battery reaches 14.5V, the regulator disconnects the alternator output or generator, weakening the magnetic field and ...
