The LM317D2T-TR is a low-dropout linear voltage regulator manufactured by STMicroelectronics. This device provides a regulated output voltage of 1.2 to 37V with a maximum current of up to 1.5A. The device is packaged in the D2PAK surface-mount package for a small footprint and easy installation. The LM317D2T-TR is adjustable, allowing for a wide range of output voltage settings that can be fixed or adjusted via external resistors. It also has a low quiescent current of only 6mA typical. The LM317D2T-TR offers excellent line and load regulation, as well as protection against short-circuit and over-voltage conditions. With its wide input voltage range and adjustable output, the LM317D2T-TR is an ideal solution for fixed and variable voltage power supplies.
