Lots of members asked about 9V dc power supply with 2A.So here We have introduce a new circuit diagram.This circuit can provide 9V 2A.I suppose now you all have some what good power supply with some what good amp level.This circuit operates with famous IC 7809.If I say simply this is a amp booster circuit.
Note
# Build this circuit on a PCB to get maximum result
# If you can attach a heat sink to the IC It will get a long life
