Power supply 12v charger voltage regulator fixed voltage 5V to 12V


 Power supply 12v charger voltage regulator fixed voltage 5V to 12V

In the field of electronic components, LM7805 is the benchmark of a three-pin linear voltage regulator. It is a positive voltage regulator whose output voltage is stable at 5 V. The LM7805 is a three-terminal positive regulator with a fixed output voltage of 5V. This fixed regulator provides local regulation.

Voltage Regulator. Learn how to make a 5V regulator using capacitors, an LM7805 regulator and a Schottky diode, learn how the circuit works and also how to build your own circuit board, how to order a circuit board and how to solder the electronic components of the circuits.

Tutorial on modifying a laptop power supply in order to use it to power a car radio (or any other device operating around 12V). The biggest job will be to identify the resistors that give the instruction to the op amp. If there is no op amp, a TL431 type voltage reference is often present.

The manufacture of this charger requires very few components. Its design makes it possible to deliver a significant intensity depending on the choice of transformer and power components: The transformer, the diode bridge and the thyristor. The regulation system based on a very stable adjustable shunt regulator (TL431) allows the charger to be left permanently connected for floating operation. the transformer must have a secondary, no-load voltage between 15.5V and 17V.
