Due to the impacts of the coronavirus outbreak, we are experiencing longer than normal lead times on certain products. We encourage back-ordering out-of-stock items to receive them as soon as possible.
This is the basic L7805 voltage regulator, a three-terminal positive regulator with a 5V fixed output voltage. This fixed regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Each one of these voltage regulators can output a max current of 1.5A.
For more information about methods of managing heat dissipation (using air, protoboard, copper PCB, heatsink, and heatsink + fan) with the 7805, try checking this enginursday post:

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

Always handy to have a stable regulated supply for sensitive electronics. This is the best way to go!
This chip design dating from the 1970s is a quick and handy 5 volt regulator for just abut anything that needs a constant voltage supply up to about 1.25 amp. A heat sink is a good idea above about 200ma.
It's great to find these are still sold! recommended.
Nothing really to say. Works like a charm!
