STMicroelectronics LM317T Linear Voltage Regulator, Adjustable, 1.5A, TO-220

The STMicroelectronics LM317T-DG is a versatile adjustable linear voltage regulator designed for a wide range of positive voltage regulation applications. Housed in a robust TO-220 (double gauge) package, this through-hole component delivers an adjustable output voltage from 1.2V to 37V while supporting a maximum load current of 1.5A. Its floating operation capability enables use in high-voltage applications, making it a flexible choice for engineers and hobbyists alike.

The output voltage is easily set using a simple resistive divider, simplifying design and reducing the need to stock multiple fixed-voltage regulators. With an input voltage range up to 40V, this regulator excels in scenarios requiring reliable and stable power conversion. The device includes essential protection features such as current limiting, thermal shutdown, and SOA (Safe Operating Area) control, alongside internally limited power dissipation, ensuring safe and dependable operation under various conditions. It maintains excellent 0.1% line and load regulation for consistent performance.

The LM317T-DG operates within a temperature range of 0°C to 125°C, making it suitable for a broad spectrum of environments. Its TO-220 package with three pins allows for easy through-hole mounting and effective heat dissipation, especially when used with a heatsink. This regulator is an ideal choice for power supply projects, battery chargers, and other precision voltage regulation tasks.
