LM317 Adjustable Voltage Converter Module - Standard Potentiometer - DIY Kit

With this do-it-yourself kit you make an adjustable voltage regulator based on the LM317.

Specifications:

• Input voltage: 5.0-25VDC, 6.0-20VAC
• Output voltage: 1.25VDC-12VDC
• Maximum output current: 1.0A
• PCB format: 60x32mm

Note: A higher possible input voltage is indicated on the PCB, however, keep the above-mentioned input voltage because the capacitor can only handle 25V and otherwise it can break.

Contents of the kit (and location on the PCB):

• 1x PCB
• 1x LM317 (VR1)
• 1x Cooling block + screw 
• 2x 0.1uF (104) capacitor (C3, C4)
