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.
