What is a power regulator used for?
Voltage regulator, any electrical or electronic device that maintains the voltage of a power source within acceptable limits. The voltage regulator is needed to keep voltages within the prescribed range that can be tolerated by the electrical equipment using that voltage.
How do I choose a power regulator?
Consider these factors when selecting a voltage regulator:
- Input Voltage and Output Voltage. Ideally, you know the input voltage range and the required output voltage that you will be working with.
- Dropout Voltage.
- Linear Regular or Switching Regulator?
- Device Sensitivity.
- Response Time.
- Power Draw.
What are the uses of a 12V adapter?
The 12 Volt Adapter Power Supply is used in: Pads, Laptop computers, lighting, mobile equipment and many more. They are now finding their way into more consumer toys, games and other home goods.
What is voltage regulator and how does it work?
A voltage regulator is basically a beefed up emitter follower, like described above – a transistor connected to a stable reference that spits out a constant voltage, dropping the rest. They also have a built in error amplifier, which samples the output voltage (again through a divider), compares it with the reference voltage, calculates the difference, and drives the output transistor accordingly.
What is a 12V DC power supply?
The 12V DC power supply is one of the most commonly used power sources today. These are switch mode power supplies which means the output is regulated to 12V. Generally, the 12VDC output is obtained from 110VAC or 220VAC inputs using a combination of transformers, diodes and transistors. Most LCD screens, hard drives, audio devices and other device needs them to work together.
What is a 12 volt power adapter?
The 12 Volt Power Adapter, also known as a “Brick”, “Desk Wart” and “Floor” supply, provide a regulated 12 Volts DC output. A 12 Volt Adapter Power Supply is enclosed in a plastic protective case that comes with either an attached AC cord, or a mating socket for one of the 3 common IEC cordsets.
