Voltage Regulator - 12V
COM-12766 ROHS
DESCRIPTION FEATURES DOCUMENTS
This is the basic L7812 voltage regulator, a three-terminal positive regulator with
a 12V 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.

SKILLS NEEDED
Core Skill: Soldering
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.

Core Skill: Electrical Prototyping
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.

Your link to the tutorial doesn’t work. Perhaps because it links to an “internal” Sparkfun page.

Should be fixed now! :)

Is there a way to have 12 volts DC, directly from an AC line (110 V), via a regulator like this one, and without
having to use an ac adapter ? (I want to use a fio or pro mini to control a light bulb in my house and I don’t
have enough space for an AC adapter) Thanks !

I used an RAC05 for a 12VAC-5VDC straight from the wall outlet. I did not use a 12VDC unit, but you can
check the links below. Its through hole and can be mounted on a PCB with your project. I purchased mine
from www.digikey.com.
Maybe sparkfun can look into carrying these units, since they are really handy to have for any control
system in the home.
