Description
dcreg12v3a mj2955 lm7812
the function of the 2955 MJ transistor is as a current amplifier, to make the output current reach Ampere unit, usually if without a transistor this circuit will only reach milli Ampere units. For the purposes of the power supply, the transistor must be adjusted constantly to the base so that the voltage exiting the emitter remains. In order to keep the base voltage steady, zener diodes are usually used. But in this series the function of the zener diode has been replaced by IC 7812.
