LM317 Linear Voltage Regulator DC Module Board – Adjustable 1.2V–37V Output The LM317 linear voltage regulator module provides adjustable DC output voltage within a wide range. Designed for applications requiring stable, adjustable power regulation, this module allows precise voltage control through an onboard potentiometer. Important Usage Note If the input voltage is the same as the output voltage, the output voltage cannot be adjusted. Before connecting to the power supply, rotate the potentiometer 20 turns anti-clockwise. After connecting to the power supply, the output voltage becomes adjustable.
