LM317P Adjustable Linear Voltage Regulator, 1.2-37V, 2.2A

The LM317P from STMicroelectronics is a versatile and robust adjustable linear voltage regulator, designed to deliver a stable and reliable DC power supply for a wide range of electronic applications. It can supply more than 1.5A of load current, with an output voltage that is easily adjustable across a wide 1.2 to 37V range using an external resistive divider. This flexibility eliminates the need to stock multiple fixed-voltage regulators, simplifying your inventory and design process.

A key strength of the LM317P is its excellent regulation performance, offering 0.1% line and load regulation to ensure a consistent output voltage even with fluctuations in input voltage or load current. It operates in a floating configuration, making it suitable for use in high-voltage applications. The device is built with robust protection, incorporating current limiting, thermal shutdown, and safe operating area (SOA) control to safeguard both the regulator and your circuit under fault conditions.

Housed in a standard TO-220FP-3 through-hole package, it is easy to mount and provides effective heat dissipation when used with a heatsink. With an operating temperature range of 0°C to 125°C, this regulator is suitable for demanding environments. Its combination of adjustability, high current capability, and comprehensive protection makes it an industry-standard choice for power management tasks in prototypes, bench power supplies, and final products.
