ordered my PCBs from JLCPCB,as low as $2, try it and register to Get $54 Coupons here:   https://jlcpcb.com/?from=PCB ---------------------------------- Gerber File https://drive.google.com/file/d/1EwFF... ------------------------------------- Hi friends in this video I will make a adjustable voltage and Ampere power supply that can regulate 0v to 30v and 0A to 1A this is very good power supply if you are bigger then definitely try to make it by ordering the pcb Or Following the diagram in video you can make it on vero board its very easy and working 100% Disadvantages Larger: Linear power supplies require a larger transformer, so they are larger and heavier than the switching power supplies. Limited flexibility . Linear regulators usually can be used with a fixed input voltage and frequency. For example, they are designed to be connected to 120 VAC 60Hz or 240 VAC power input.  If you want to use 240 VAC power, you need to switch taps on the input transformer. Limited outputs . Linear regulated power supplies only provide one output voltage. If you need more, you’ll need to add a separate linear regulator per required output. Poor efficiency. The average linear regulated device achieves an efficiency between 30%-60% due to heat dissipation. It also requires a heat sink, which adds to the device’s size and weight.
