Applications

• Manufacturing industry

• Medical technology

• Agricultural equipment

• Computer devices

What's the difference between a switching regulator and a linear regulator?

While a switching regulator stores excess voltage in its transistor leading to lower energy waste, a linear regulator releases excess voltage as heat. As switching regulators use less power and are more efficient, you'll typically find them used in devices with high input voltage ratings.
