Very Smooth Constant Power Supply

Normally voltage of the main electricity bord is not at constant value. This will affect to our some electric appliances.Constant supply of voltage is very essential for some electronic circuits. so we can use a voltage regulator to over come this effect. "78" series voltage regulators are most suitable for this. As there are lot of different voltage regulators in this series you can make power supplies according to your choice.

You can select the regulator using the picture shown below.
