LM317 DC-DC Adjustable Converter Buck Step-Down Power Module

Description

The LM317 DC-DC Adjustable Voltage Regulator Power Supply Module is a power supply module that utilizes the LM317 adjustable voltage regulator. It is capable of delivering more than 1.5 Amps of current and offers an adjustable output voltage range from 1.25 to 37 Volts.

The module simplifies the voltage adjustment process by providing onboard potentiometers that act as the required resistors to set the output voltage. This eliminates the need for external components and makes it easier for users to adjust the voltage. The module also features input and output filter capacitors, which help reduce noise and improve the stability of the output voltage.

The LM317 DC-DC Adjustable Voltage Regulator Power Supply Module has two sets of two-way connectors for input and output DC voltages. These connectors facilitate the connection of power sources and load devices with ease. The input method for the module involves connecting the Vin input to the desired input voltage level and the GND input to the negative terminal of the power source. The output is obtained from the Vout output terminal, providing a positive voltage, while the GND output terminal provides a negative voltage reference.
