LM317 DC-DC Converter Buck Step Down Circuit Board Module Linear Regulator LM317 Adjustable Voltage Regulator Power Supply

Description

The LM317 4.2-40V to 1.2-37V 1.5A DC-DC Step-Down Power Converter Module is an electronic circuit for converting a DC source voltage from one level to a lower level. This module is important in some portable electronic devices such as cell phones and laptops, which are primarily supplied by power from batteries. The step-down voltage can be easily adjusted and is therefore more efficient than using multiple batteries to achieve the same thing.
