Here is a project of a 12V to 8V converter using the LM7808 IC, which subsequently lies in the category of Power supply circuits. Meanwhile, the circuit is utilizing an LM7808 IC to convert 12 volts DC supply to 8 volts DC supply.
Although, the LM7808 IC arrangement of three-terminal positive controllers is accessible in the TO-220 bundle and with a few fixed yield voltages. Meanwhile, these characteristics make them valuable in a broad scope of uses. Each type of IC in the series utilizes interior current restricting, thermal shut down, and safe operating condition insurance. It likewise makes it indestructible.
On the off chance that adequate thermal sinking is accessible, they can convey over 1A yield current. Albeit it is planned essentially as fixed voltage controllers. However, these electronic gadgets utilize outer segments to acquire flexible voltages and flows. More details are mentioned in the sections below.

12V to 8V Converter Circuit
Circuit Operation
The circuit is exceptionally straightforward, utilizing just three segments. The core of the circuit is an LM7808 fixed voltage controller IC. It is a decent IC with many forms in highlights like thermal over-burden security, hamper, safe operating assurance, and so forth. The yield current is up to 1A, which is reasonable for most electronic gadgets. The info voltage can be any from 12V to 35V DC. However, it is advised to utilize a sizeable thermal sink for voltage over 20 volts. The supply voltage source can be a 12-volt battery or any 12V to 35V yield transformer with 2A current appraisals. A 2A connect rectifier for changing from AC to DC, and an electrolytic capacitor will be required with the transformer.
Applications and Uses
