Description

The LM317 Adjustable Voltage Regulator is a versatile three-terminal positive linear regulator IC designed to provide an adjustable and regulated output voltage for electronic circuits. It allows the output voltage to be set from 1.25V to 37V using external resistors, making it useful for a wide range of power supply, electronics repair and DIY applications.

With an output capability of up to 1.5A when properly heatsinked, the LM317 can be used in adjustable power supplies, voltage control circuits, battery-related projects and many other electronic applications. The device also incorporates internal current limiting and thermal overload protection.

The TO-220 package makes the LM317 convenient for PCB mounting and applications where a heatsink may be required for higher power dissipation.
