Fyearfly L7805 - 5 V linear voltage regulator, 10 pieces

The L7805 is a classic three-terminal voltage regulator that turns a higher input voltage into a steady 5 V. It is a staple of power supplies for digital circuits, microcontrollers, Arduino modules and LEDs. The set contains ten pieces in a TO-220 package.

How it works

The chip is a positive linear regulator. It has internal current limiting, thermal protection and safe operating area protection, so it is hard to damage with typical wiring mistakes. Under heavy load and with a larger voltage difference it dissipates heat, so it is worth mounting it on a heat sink.

Parameters

Applications

• regulated power supplies for electronic circuits,
• local voltage regulation on a board,
• powering LEDs and simple modules,
• repairs and prototypes.

The 10-piece set is handy for hobbyists who want a regulator on hand for upcoming projects. The chip is no substitute for a switching converter where the voltage drop is large, because it turns excess power into heat.

The L7805 voltage regulator is the simplest 5 V regulator, and every integrated circuit in this set follows the same proven operating design.
