These are an incredible value. 96-98% efficiency means NO HEAT and NO WASTED POWER.. the days of the TO-220 1A regulator with heatsink and fan are over.
It brings shame to what I used to think was an efficient power supply after matching transformer, rectifier, heat sink, and convection cooling.
There are two; a 1.8A and a 3A and they are both terrific regulators - power supplies made simple!

** And just as a side note: they arrived faster than a similar order for FETs from Amazon!

Q:
Is this version also overheating? what I have are Without load, the inductance went up to almost 80 degrees for me, unfortunately after the load I connected it didn't get any better. They had 60-70 mA in consumption without load.

A:

I have used this module in different circuits. Have not detected an overheating. Use it up to approx. 1.4 A. I am very satisfied, everything works without problems.
