What is the function of voltage regulator?
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.
Which type of voltage regulator is best?
switching regulator
When high efficiency is needed, or a wide range of input voltage is expected, a switching regulator becomes the best option. Switching voltage regulators have power efficiencies of 85% or better compared to linear voltage regulator efficiencies that are often below 50%.
What are the different types of voltage regulator?
There are two main types of voltage regulators: linear and switching. Both types regulate a system’s voltage, but linear regulators operate with low efficiency and switching regulators operate with high efficiency.

What is the output voltage of a 7805 IC?
A Brief Note on 7805 Voltage Regulator. 7805 is a three terminal linear voltage regulator IC with a fixed output voltage of 5V which is useful in a wide range of applications. Currently, the 7805 Voltage Regulator IC is manufactured by Texas Instruments, ON Semiconductor, STMicroelectronics, Diodes incorporated, Infineon Technologies, etc.
What is the pinout of the 7805 voltage regulator?
Here is the 7805 5V voltage regulator datasheet and the 7805 pinout. They are designed to provide a constant 5V. When powered by from about 7.3 to 35 volts. We usually want to use a stable voltage source. Which it is a lower voltage than batteries. Sometimes, transformer power supply may have high voltage.
Who is the manufacturer of the 7805 IC?
Currently, the 7805 Voltage Regulator IC is manufactured by Texas Instruments, ON Semiconductor, STMicroelectronics, Diodes incorporated, Infineon Technologies, etc. They are available in several IC Packages like TO-220, SOT-223, TO-263 and TO-3.
What happens if the 7805 regulator is overheated?
Internal overload protection: If the 7805 regulator IC operates over too much and starts to overheat. A special thermal overload circuit will automatically turn off the chip until the temperature returns to a safe level. The minimum input voltage to deliver 5 volts output: 7.3V. below 7.3V the chip may not provide a stable 5 volts.
