β Used to stabilize output voltage.
A voltage regulator is designed to maintain a consistent output voltage despite variations in the input voltage or load conditions. This stabilization is crucial for electronic devices that require a specific voltage to operate correctly. If the voltage fluctuates too much, it can lead to malfunction or damage to the device. The regulator ensures that the output remains within a certain range of the desired voltage.
Think of a voltage regulator like a thermostat in your home. Just as a thermostat keeps the temperature in your home steady, regardless of external weather conditions, a voltage regulator keeps the voltage supplied to your electronics steady, regardless of fluctuations in the power supply.

β Common in low-power regulated power supplies.
Voltage regulators are commonly found in various low-power applications, such as in power supplies for microcontrollers and other small electronic devices. These settings often require specific, stable voltage levels to function correctly without being disrupted by voltage changes from the power source.
Imagine charging your smartphone. The charger has a built-in voltage regulator to ensure that your device receives the correct voltage for optimal charging. If the voltage were too high or too low, it could either overcharge the battery, damaging it, or fail to charge it at all.
