## Description

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 1.5A Max Output Current – Sufficient for most small to medium loads Built-In Protection – Current limiting, thermal shutdown, and safe area protection TO-220 Package – Through-hole with heatsink tab Simple to Use – Only requires two resistors and input/output capacitors Ideal For Custom adjustable power supplies Local voltage regulation in circuits Powering sensors and modules at non-standard voltages Learning about linear voltage regulators Package Contents 1× LM317TG Adjustable Voltage Regulator (TO-220)
