Today I has 12V to 5V 3A DC converter step down Regulator circuit come to deposit. In sometimes friends have power supply 12V 3A , but want Voltage 5V 3A for digital Circuit. This circuit can meet the demand of friends get , by it uses normal electronic part and have 7805 integrated circuits perform [...]
Friends that seek 5V 10A power supply circuit small-sized and build easy. I begs for to advise this circuit. It is 10A switching regulator by use IC L4970A. Then build easy as an example integrated readymade circuit. Important point be power supply input must have 10A current sizes then can give power get enough. The [...]
Friends at like to experience is digital circuit has evered to get into trouble have no 5V lab power supply ? In time wants emergency. but seek buy the integrated circuit can not. We come to try use the transistor be 5v voltage regulator circuit better. A friend who have old equipment may sure lollipop. [...]
