The LM317-N is a 3-terminal adjustable voltage regulator capable of delivering up to 1.5 A of output current with an adjustable output voltage range from 1.25 V to 37 V. It features excellent load regulation of 0.1% and line regulation of 0.01%/V, making it suitable for applications requiring stable voltage output. The device operates over a wide temperature range of -55¬8C to 150¬8C, ensuring reliability in various environments. It includes built-in overload protection, such as current limiting and thermal shutdown, which remains functional even if the adjustment terminal is disconnected. The LM317-N is designed for ease of use, requiring only two external resistors to set the output voltage, and typically does not require additional capacitors unless located far from input filter capacitors. This regulator is ideal for applications in multifunction printers, AC drive power stages, electricity meters, and servo drive control modules.
