        One of these has been working fine with the amateur radio fitted to my Explorer, driving the OEM amplifier. Now I will use one to regulate supply to replacement digital meters on a home power supply. I revised the voltage up to 9V per the nice description by N1HFX

            Got 2 of these to use in home made power supplies. One was running at around 4.88 vdc at idle. The other was around 4.98 vdc at idle. Replaced the first one and had a reg. that was running at 5.05 vdc. If your looking for very god regulation, look somewhere else for your parts. For what I use them for, its ok. But I wouldn`t trust them for anything other than hobby use!(and be careful even at that)

                Needed to replace the Sirius power supply from a stupid taped up cigarette plug.
                Wired a 7805 with a TO-220-TO-202 heat sink and it works perfect.
                The Sirius only draws 1/2 amp so the small heat sink is plenty.

                Comments about RadioShack +5V Fixed-Voltage Regulator 7805:

                I bought this regulator to supply a volage for a fairly sensitive microcontroller and upon installation in the circuit, the first one sat at 6v and stayed there even with modest loading.

                I returned the product for another one, thinking that it was just a bad unit, the replacement was still at 5.8v under load.

                Asked about the source and nobody can tell me what company sources the part to RadioShack. Ended up returning the product since it was not suitable for my uses.

                  Works great. I have the Gigaware™ Universal Portable Speaker System for MP3 Players, and it has a power input that requires 5V and 1A. That power supply isn't really sold for cheap. This was perfect for it. Now I have a usb power cable and I don't have to use up all my AAA batteries.

                      i used it to charge my cellphone on the go. i wired everything up correctly, plugged in a 9v battery, plugged in the charger, and it charges my env3. it also runs anything you can think of that requires 5v to operate. it does create a good amount of heat but that's always a given when working with and type of regulator/transistor.

                      I used the regulator to make an iPhone charger. It worked perfectly, gets a bit warm drawing 500mA. I was going to use the LM317 because I thought RadioShack wouldn't have a 5v regulator, but then I found this. Works great, put out 5.04 volts. Make sure to anchor it to something with dissipating abilities though. I was making a minty boost and screwing it directly into the mint tin worked great.
