AMS1117-ADJ step-down power module power stabilivolt chip 1. Overview The voltage of the LC AMS1117-ADJ module can be adjusted. In order to guarantee the stability of the output, it is necessary to keep the pressure differential of 1.5V. 2. The function and characteristics Input voltage: 5V-12V Output voltage: 2.5V-10.5V Low-volt leakage: Only 1.2V when 1A current output Output voltage accuracy: 1% Temperature range: -40~125 Other features: Limit current function/Overheat cut off 3. Introduced the hardware and instructions The board size: 49*18.2mm The board function description: DC bridge: The power input VOUT: Output voltage of the anode GND: Output voltage of the negative Rotate the potentiometer can change voltage: Clockwise booster, counterclockwise step-down.
