An LM317T Adjustable Positive Voltage Regulator is an adjustable 3-terminal linear regulator capable of supplying over 1.5A across an output voltage range of 1.25V to 37V. Encapsulated in a standard TO-220 package with an integrated metallic mounting tab, it maintains a precise 1.25V reference voltage between its output and adjust terminals. Printed clearly with part number "LM317T" (STMicroelectronics branding), it features three terminal pins: Adjust (Pin 1), Output (Pin 2 / Mounting Tab), and Input (Pin 3), equipped with internal current limiting, thermal overload protection, and safe-area compensation.

This product is featured by Famephase Electronic Accessories as a core power management component for variable benchtop power supplies, precision current limiters, programmable output power supplies, battery chargers, and adjustable linear bias rails.
