Voltage Regulator - Adjustable

The LM317TG is a three-terminal adjustable positive voltage regulator with an output range of 1.2V to 37V and up to 1.5A output current. Only two external resistors are needed to set the desired output voltage, making it one of the simplest ways to create a custom voltage supply for your project.

Built-in protections include internal current limiting, thermal shutdown, and safe operating area protection — ensuring reliable operation even under fault conditions.

Key Features

• Adjustable Output – 1.2V to 37V, set with two external resistors
