Lm7815 Voltage Regulator PCB protection tool Type Designator: 2SA1273We all very well know regarding the building procedures a DC power supply circuit using a transformer, a bridge rectifier and a filter capacitor. It just requires connecting four diodes in a bridge configuration and connect it to the secondary of the transformer, the capacitor goes to the output of the bridge terminals. The output produced across the capacitor is approximately equal to the rated voltage of the transformer, rather a few volts higher
