### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Simple, high quality, regulated voltage
  

*by M***D on Reviewed in the United States on December 31, 2018*

Very well made product. If you need consistent pre-set DC voltage for your maker applications, this does the job.  Minimal voltage drift and the adjustment screw is not too temperamental.  It takes several turns to adjust voltage output levels. The PCB construction and component mounting are all high quality. Has nicely detailed touches, like the through-board pins being sanded down and the input & output voltage ranges being silk-screened on the bottom.  The potentiometer direction instruction for the voltage pot is simply exposed gold? trace, so it can't be scratched off.  All PCB mounting holes are via reinforced (grounded). The width between mounting holes also matches Arduino mounting specs.If you have few thousand dollars worth of equipment depending on a pre-set voltage, this high quality voltage regulator adds one more level of insurance against potential over-voltage damage.Update: The review above was written for the DROK LM2596 Immersion Gold Voltage Regulator. Currently this review was put under another product heading. My comments only apply to the Immersion Gold version.Update2: Ordered 2 more Immersion Gold versions only to find both are missing their adjustable potentiometer!!! They only regulate to a fixed 12 volt output with a resistor soldered in place of the pot, but the page says they have an imported BI potentiometer.

    Low RF noise
  

*by M***K on Reviewed in the United States on August 24, 2019*

Used this in a clock that has a receiver at 5, 10 and 15 MHz for picking up the WWV.  I tested several buck converters and this one was the quietest at those frequencies without needing shielding.  It is a bit noisy at 5Mhz but still better then the others I tried.  Very well built.  Worked so well that I bought another.  Well worth the price.

    Very nice regulator
  

*by K***9 on Reviewed in the United States on December 5, 2018*

Well built and works great.  Very fine voltage adjustment.  It's a bit of overkill for my application; I'm using it to drop 5V at 300mA, and it's not generating any heat at all.  The green status LED is blindingly bright.
