I am trying to build a 5V constant 3A DC circuit. As stated in this datasheet: http://www.ti.com/lit/ds/symlink/lm338.pdf on page no.15.
According to calculation R2= 1.28 ohms, but I don't have it I have 1.6 near to it.
I have created the circuit using R2=1.6 ohms resistor and placed a 1K resistor as load and checked the voltage across it, it is giving me 15.68V which is a problem.
How can I accomplish this?
As stated in this datasheet: ti.com/lit/ds/symlink/lm338.pdf on page no.12. I have created the circuit and it is giving me 5.1 V constant just want to ask for confirmation that current drawn through this ckt will depend on load right? and we can take out max 5A right?
