      Used it to step 12v down to 5v for a bluetooth serial adapter on my Buell 1125r. This module operates consistently at +/- 0.2v and has resisted temperatures of over 150 degrees.

          I bought one of these to use in my solar charging circuit. The first one burned out and stopped working completely.
          I bought another one, and it's now putting out 9 volts and blowing my chips.
          I now have to buy another one... this time some where else.

          Works, But Extremely Hot

          By Cole

          from IE

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

          It works fine and regulates it slightly under 5, but within 2 seconds of powering on, it gets too hot to touch. It only does this when it has a load on the output. Im worried that it will melt down and let voltage through...

              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.
