12Volt Transformerless power supply

This is a 12V 100mA Transformerless power supply in support of low current applications. C1 is the X rated AC capacitor so as to reduces climax volt AC. D1-D4 rectifies AC to DC and C2 removes ripples. R1 is the bleeder to remove stored current clothed in AC while power is rancid. R2 limits inrush current. A Zener can stay used in the output to pick up regulated DC.
