Voltage regulators are designed to maintain and stabilize voltage levels. Regulators are found in most electronic devices and can be used to step down and control voltage outputs from a high voltage source, dissipating excess energy as heat. This is great for applications where you need multiple discrete voltages for different devices within a single circuit because you can use voltage regulators to step down from a single higher output source!
Most voltage regulators have 3 pins:
Input – This is the input voltage from the original source. For example a battery or a power supply. You feed the output of this device into the input of the regulator. The input should always be as clean as possible and should always be above the required output voltage. Most voltage regulators have a specified minimum input voltage, so be sure to follow it (otherwise the output may be lower than expected)
Ground – A common ground is required between the input and output voltages. This must connect to ground in the circuit and is necessary for the operation of the regulator.
Output – The output pin spits out the regulated voltage.
How to use voltage regulators in a circuit?
The operation of voltage regulators is a subject in itself, so we will not detail it here. Suffice to say, voltage regulators are essentially voltage sinks that convert excess voltage into heat. A higher input voltage will result in a hotter voltage regulator as it works harder to get rid of this excessive voltage, so users should be aware of this!
Your wall outlet produces AC, while most appliances are DC. One of the functions of a power supply is to step down and convert this AC signal to DC, but there may be "noise" on the line depending on the quality of the power supply used, which can cause problems with voltage regulators.
If your regulator is located more than 25 cm (10 inches) from the power supply, you will need to add capacitors at the input (0.33uf) and output (0.10uf) to filter out any residual AC noise on the line. Voltage regulators operate most efficiently when a clean DC signal is fed, and these bypass capacitors help reduce any AC ripple. Essentially, they act to short circuit AC noise from the voltage signal to ground and filter only the DC voltage in the regulator.
These two capacitors are not necessarily necessary and can be omitted if you are not too concerned about the amount of line noise, e.g. if you add some LEDs with resistors. However, if you're building something like a cell phone charger or using the output for logic evaluation, you'll want a nice clean DC line, so we recommend including the capacitors!
The 0.33uF ceramic capacitor should be connected after the voltage source and before the voltage regulator input. The second capacitor, the 0.1uF ceramic capacitor should be connected after the output of the voltage regulator.
In the circuit above we have a 12V source, which we need to regulate to 5V to run our LED! The GND in this circuit is simply the negative side of this 12V source.
The first 0.33uF capacitor shorts out any AC noise on the line to ground and cleans up the signal for our regulator input. The regulator in this circuit is a TS7805CZ (5V 1A) regulator, which then pulls the 12V voltage signal down to 5V and pushes it to the output.
The 0.1uF capacitor then cleans up the DC signal, leaving us with a nice clean 5V source. We can use to power any 5V device, in this case an LED, but you can connect any 5V device at this point!
There A few things to consider when using voltage regulators in a circuit:
Always check the “OUT” voltage with a multimeter before connecting your circuit. The last thing you want to do is blow up your 5V device pushing a big voltage by mistake
Most regulators only have 3 ports (IN / OUT / GND). If there are more pins, make sure you know what they do and if foreign components are needed.
Excessive voltage is dissipated as heat by the regulator, so take care when designing and using circuits. If you reduce a high voltage, more heat will be created by the regulator, and you may need a heat sink to make sure your regulator doesn't burn out. If it's too hot, it's probably too hot!
