Simple power supply circuit provides variable output voltage 1.2V to 15V DC and load current up to 3 Amps, onboard trimmer pot provided to adjust the output voltage. Output capacitor C3, C4 provided for transient response, the circuit can take DC input as well as AC input, maximum DC input 15V DC and AC input 12V AC. LM1084-adj IC is heart of the project.
Note : The same PCB can be used with other regulators like LM1085-ADJ, LM1086-ADJ and LM317-ADJ, for higher supply input change the Input filter capacitor voltage.
