Car audio amplifier
If you need 3A power supply. We recommend the LM317 adjustable voltage regulator circuit. It use normally component LM317 popular DC voltage regulator and 2N3055 transistor to boost up current to maximum 3A. We can select voltage adjust voltage in steps 3V, 6V, 9V, 12V. adjust continuous 1.25V to 20V. Learn more now!
