7805 +5V Voltage Regulator TO-220 is rated 4.6 out of 5 by 5.
Rated 3 out of 5 by from Looks fine but yet untested.Looks fine but yet untested.Professional appearance.No instructions included.

Rated 5 out of 5 by from Works GreatI used this along with 220uF and 47uF capacitors and hooked it to the output of a 7809 regulator to create 9V and 5v outputs on a 12V power supply. They work great! For my use the 7805 got extremely hot so I put it on a heatsink from an old computer PSU.. made a world of difference as it doesn't even get warm to the touch anymore. Excellent product and parts express was quick to ship as always!***the datasheet can be found on the Fairchild Semiconductor website, just navigate the products page to the voltage regulators***

Rated 5 out of 5 by from Better audio from portable radioI used this to build a substitute AC adaptor. The regulation lessens the AC hum in audio normally introduced by common AC adaptors.

Rated 5 out of 5 by from Excellent RegulatorThis one regulates my powersupply at 4.97 Volts, could be that my voltmeter is only accurate to 2 significant figures, which in that case it would be 5.0 Volts exactly.

7805 +5V Voltage Regulator TO-220

I am purchasing the MP3 player (#320-350) and the DTA-2 Amp to run a power horn speaker.  I will be using a 12V battery to supply power to both.  It is my understanding that I will need a 5V regulator to convert the 12V.  Where does the regulator go??

It was asked before if you could use this to wire a 5V bluetooth device to a 12V tripath amp board so that both could be powered from a single source. Will the amp still have enough voltage to be properly powered?

Asked by: slopps
Yes this will work for that application and will not effect the power to the amplifier.

Can this be used to split off a 110 to 5v .    Also I would need a mini jack to be able to use from the source a 110 power source in a lighting unit to 5V mini jack out to wireless unit , which is now having to be connected via a Wal wart.

Asked by: Polkadotjones
NO....no...no...firts of all the 110V in AC..? correct..? This is a DC voltage regulator, so the input needs to be DC and not AC...If you look in the data sheet of this component you will find the max. voltage for the input, the more close the input volage is to the 5V output the less warm it will become...There is a min. input voltage for it to work properly, you can find that in the data scheet too...The proper way to go is take a Wal wart with a DC output of about 12V and put this regulator behind it to make 5V DC....again look in the data scheet, in order for it to work good without occilation it needs some capacitors on the in and output....An other way to go is making your own TBC power supply. (transformer/bridge rectifier/capacitor)....but you need some basic knowlage how to calqulate this solution...

12V to USB charger?

Can I wire this between a 12 volt battery and a female USB port to charge an iPod/cellphone?Where do I solder it?
Asked by: Johnny V
Yes, this voltage regulator would be suitable to use a +12v power supply and convert to +5V for USB charging. The listed max output current is 1 amp, and based on the USB spec sheet I am reading, looks like the max current draw for USB devices is 900 milliamps, so this regulator should work for your needs.Pull up your favorite search engine and type "7805 datasheet" to get the tech specs on this regulator. Look for the Fairchild Semiconductor datasheet.As for wiring, I would use the circuit Fig. 5 on page 21 of the datasheet. I have heard of people running these regulators without shunting capacitors, but I would follow the manufacturer recommended circuit.You should be able to search a USB pinout in your favorite browser also to get a diagram of which pin on your USB connector to wire to the +5V output from the regulator.
