1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups.

12v regulated power supply circuit diagram. It has many built in features like thermal shutdown short circuit protection safe operating area protection etc. Making a fixed 12v regulator circuit. In the above diagram we can see how an ordinary 7805 regulator ic could be used for creating a fixed 5v regulated output. Here is a very simple and useful project of a 12v power supply circuit using lm7812 ic.

Here this circuit diagram is for 12v regulated fixed voltage dc power supply this power supply circuit diagram is ideal for an average current requirement of 1amp. A lot of 6v supply. Regulated power supply block diagram. In case you wanted to achieve a fixed 12v regulated power supply the same configuration could be applied for getting the required results as shown below.

It has short circuit protection thermal overload protection. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. First power supply circuit is built with bd139 one zener diode and a few passive components. Regulated power supply is an electronic circuit that is designed to provide a constant dc voltage of predetermined value across load terminals irrespective of ac mains fluctuations or load variations.
