The LM317AT with Linear Voltage Regulators 3-Term Adj Reg is a three-terminal adjustable voltage regulator manufactured by Texas Instruments. This voltage regulator has an output current capability of 1.5 A and can be used to provide an output voltage range from 1.2V to 37V. It is available in a wide variety of packages, and is designed for use in a wide range of applications. It features short-circuit protection, current limiting, thermal shutdown, and automatic reset. It also includes two symmetrical voltage references, one for setting the output voltage and one for controlling the current limit. The LM317AT is ideal for providing accurate and stable supply voltages for digital and linear circuits.
