A very good and honest seller. I tested the chip with LT1083CP and it works fine. The LT1083CP is genuine which is rare on Aliekspress. At 5A and 13.8V, the voltage drops only 0.15V. This is a very good result. Thank you very much seller. I am happy to buy this kit again, and if there is a possibility, I will buy these LT1083CP chips from this seller.
Very good! Many thanks!!!
