Adjustable Lab Power Supply 2V-20V 5A


Adjustable Lab Power Supply 2V-20V 5A
Adjustable Power Supply is a one of the first things the electronics hobbyist must have. But if you think to buy a good power supply it will be pretty expensive.
So I built a power supply for my self. The hart of this power supply is LM723.

General Description about LM723 according to the Data Sheet
The LM723 is a voltage regulator designed primarily
for series regulator applications. By itself, it will supply
output currents up to 150 mA; but external transistors can be
added to provide any desired load current. The circuit fea-
tures extremely low standby current drain, and provision is
made for either linear or foldback current limiting.

There are loads designs freely available over the web for this Reg. IC.
And this is just another design.

I am K.G. Pasan Laksiri Karunanayake and founder of OptoElectronics.lk. Since 2011 I have specialized in designing custom electronics for industrial applications. Over the years I have engineered a broad range of custom industrial products. When I work with a client I place a very high value on integrity, honesty and clear communication. With years of field experience I have learned that all business relationships are personal relationships. The more I know about the client and his project, the more I can contribute to a successful end product. After I learn about the client requirement I always give them the better understanding and clear picture about, how the end product will function in real world. In addition to the client requirement, I also offer lots of options, features and improvements. And I always very concern about the end product quality.
