This is the LM317TG voltage regulator, a three-terminal positive regulator with a 1.2V to 37V adjustable output voltage. This adjustable regulator provides a local regulation, internal current limiting, thermal shut-down control, and safe area protection for your project. Did we mention that this guy is easy to use? It only requires two external resistors to set the output voltage. Each one of these voltage regulators can output a max current of 1.5A.

Features:

• Output Voltage: 1.2V - 37V Adjustable
• Output Current: 1.5A
• Thermal Overload Protection
• Short Circuit Protection
• Output Transistor Safe
• Floating Operation for High Voltage Applications
