10Pcs LM317 Adjustable Power Supply Board DC-DC Buck Linear Regulator
- LM317 Linear Regulator Board: This LM317 adjustable regulated power supply board is designed for DC voltage regulation and small electronics projects. It can be used as a simple adjustable bench power module for DIY circuits, sensor testing, microcontroller experiments, and repair work.; Wide 4.2V to 40V Input Range: The module supports a DC input voltage range of 4.2V to 40V and provides an adjustable output voltage from approximately 1.2V to 37V, making it suitable for generating common test voltages such as 3.3V, 5V, 9V, and 12V.; Adjustable Output with LM317 Regulator: Based on the classic LM317 adjustable linear regulator, the output voltage can be set according to project requirements. It is convenient for powering different modules, testing circuits, and building simple regulated power supplies.; Linear Regulation with Low Ripple Output: As a linear regulator module, it offers simple operation and relatively low output ripple compared with many switching converters. Please note that this is a step-down regulator, so the output voltage must be lower than the input voltage with sufficient voltage difference for stable operation.; Compact PCB Power Module: With a small 35.6 × 16.8mm PCB size, this module is easy to install in electronic prototypes, lab fixtures, control boxes, and educational projects. For best results, adjust and verify the output voltage with a multimeter before connecting your load, and provide adequate heat dissipation for higher current use.
