LM317T Adjustable positive voltage regulator integrated circuit that you can use for the module pcb drawing printed circuit dimensions are quite small connected with a potentiometer cable for voltage adjustment. LM317T pcb has a rectifier part bridge diode (4 pieces of 1n4007 can be used), filter capacitor (1000uf) etc.
just connecting the transformer output is enough if you want to use it in dc sources (pc power supply, dc adapter etc.) there is no need to use 1000f capacitor by the way 1000uf in the diagram and 100uf at the output is 25v if you are going to do justice to the integrated and use it at the highest voltage level between 1.2v and 32v the voltage of all capacitors should be at least 35v.
