Voltage regulator as a central component of electronics

Electronic devices of all kinds require a constant operating voltage at a fixed level. The input voltage of power grids, batteries, etc. often exceeds this value, in which case it is essential to minimize this voltage: This is achieved by step-down voltage regulators, also known as step-down voltage regulators. They reduce the input voltage to the desired level of the output voltage. Is the input voltage too low? Then a step-up voltage regulator provides a remedy.

These two basic types as well as step-up/step-down voltage regulators and shunt regulators are available here in the store in numerous versions. Whether you are a craft business, industrial company or ambitious hobby electronics engineer: equip yourself here with brand quality voltage regulators!

Different types of voltage regulators

If you need a voltage regulator for your project, the first step is to decide what specific function it should perform. Choose between these types of voltage regulators:

The step-down voltage regulator

This type is a buck converter that reduces a high input voltage to a lower output voltage. A crucial question is what reduction the voltage converter achieves. What maximum input voltage does it minimize to what level?

The step-up voltage regulator

The boost converter increases a low input voltage to a higher level. The minimum and maximum values for the input and output voltage are also of interest here.

The step-up/step-down voltage regulator

With a buck-boost converter, you get a regulator that can perform both tasks. These flexible buck-boost regulators guarantee a constant operating voltage in a dynamic environment.

The shunt controller

These are classic cross regulators which, unlike switching regulators, are intended for low power and can only reduce voltage. This variant requires a current limiter, which is implemented by those responsible with an upstream resistor, for example. One advantage is the low price; the disadvantages include limited application possibilities and inefficiency.

Innovative switching regulators instead of linear regulators

In practice, efficient switching regulators have become established, while linear regulators such as shunt regulators only play a minor role. Whether step-down voltage regulators or step-up/step-down regulators: modern switching regulators reliably fulfill their function - and do so with a high degree of efficiency!

The advantages of switching regulators at a glance:

  • high efficiency
  • excellent thermal output
  • wide voltage difference possible
  • designed for higher currents

Bear in mind that you often need additional components such as capacitors for switching regulators. Let your electrical engineering experts advise you!

Frequently asked questions about voltage regulators

Where are voltage regulators used?

These regulators can be found in numerous electronic components. Basically, they are used wherever you want to convert a specific input voltage into a constant output voltage. The range is huge: in computers and consumer electronics, for example, you use voltage regulators with low performance data, while in systems engineering you often use more powerful models.

Can I use voltage regulators with a Raspberry Pi?

This is easily possible with the corresponding models. For most voltage regulators, you will find this specific information in the product details: The manufacturers explicitly indicate whether regulators are suitable for a Raspberry Pi as a router or in another function.

How do I choose the right voltage regulator?

Numerous aspects deserve attention here. For example, it depends on which basic function the regulator is to perform. Reduce voltage, increase voltage or both? The specific performance values such as the minimum and maximum operating voltage and the maximum output current are also of interest. Also look out for extras such as overheating and short-circuit protection!
