Hi all, i am new to electronics and i am doing this as a project.
I am using LM317T voltage regulator to regulate a voltage source of Vin = 5.47V and the output Vout = 5V. Refer to attached below.
Base on the calculation, i can get Vout to be 5V. But when i connect up the circuit, my Vout becomes 3.92V, Vadj = 2.92V.
As i read online, if Vadj is connected to ground, the reference voltage will be 1.25V.
Please advise as i am not sure if my understanding is wrong or my calculation is wrong. Thank you.
