Frequently asked questions
How do I set the output voltage?
Connect the input supply and a multimeter to the output, then turn the adjustment potentiometer until the meter shows the required voltage. Set it before connecting your load.
What input voltage should I use?
The input can range from 4.5 V to 50 V, but it must stay above the output voltage you set because the regulator needs headroom. The listing description gives 3-35 V output while its title says 3-40 V, so verify the range with a meter.
