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.
