LM317 Module - DC-DC Converter Adjustable Linear Regulator

From Micro Ohm's description

LM317 DC Linear Regulator, DC-DC 4.5~40V Turn 1.2~37V, Step Down Power Module, Adjustable The LM317 DC-DC converter 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. Features of LM317 Module : Output Current: 1.5A (Min.), 2.2A (Typical) Input-Output Voltage Differential (VI-VO): 40Vdc (Max.)
