About this product
An LM317-based adjustable voltage regulator module that accepts 4 to 40 V DC and provides an adjustable output from 1.2 to 37 V, up to 1.5 A with a heatsink. It is used to supply a stable, adjustable voltage to microcontroller, sensor and prototype circuits. Because the LM317 is a linear regulator, it dissipates excess input voltage as heat.

Why does the module get hot?
The LM317 is a linear regulator, so the power it wastes equals (Vin - Vout) x Iout. For example, 12 V in to 5 V out at 1 A wastes about 7 W as heat. Use a heatsink at higher currents or a smaller input-output difference.
How do I set the output voltage and what input margin do I need?
Turn the on-board potentiometer while measuring the output with a multimeter. The LM317 needs about 2 to 3 V of headroom above the output, so the input must stay at least that much higher than the voltage you want.
