With this simple DC voltage converter circuit we can reduce 12v to 5v symmetric voltage and can use existing resources.
Here used 3-Terminal Adjustable Regulator LM317 for positive regulation and LM337 for the negative regulation. The maximum output current is 1A, and as always highly recommend a good heat dissipation for this IC regulator.

We see that almost all of which are available today in addition to the microcontroller powered by a battery. But if we do not want a 5V in many cells in series … You can use the Converter 3v to 5v circuit described here.
57V variable power supply up to 1.5 A

In each workshop you must have a source that is able to provide each current and voltage in a quite acceptable range of possibilities. This variable power supply device goes beyond the conventional power supply source (which rarely exceed 24V output) gives the maximum 57V with 1.5A current.
Variable 4 A/25V Power Supply
On May 2nd, 2012 by psu | No Comments | Posted in Regulated Power SupplyAll workshops or laboratories must have a power supply for general purpose that can supply voltages and currents.
This time we get a adjustable power supply with output voltages between 1.2 and 25V the maximum current of 4A. This is very useful for laboratory power supply or workshop power supply.
35V adjustable power supply 1.5 A
On April 28th, 2012 by psu | No Comments | Posted in Regulated Power SupplyOne of the most needed instruments in electronics lab is adjustable power supply, allowing you to feed each circuit is tested or constructed for the required voltage and current. 
The adjustable power supply circuit shown here is just a linear power supply, a bridge rectifier and filter capacitor that it attach series voltage regulator. Furthermore, here was provided by a pair of fixed instruments that allow us to know at any time the voltage given in the output and load current used.
