STMICROELECTRONICS LM317T Adjustable Voltage Regulator

The LM317T is an adjustable positive voltage regulator capable of delivering over 1.5A of load current with an output voltage range of 1.2V to 37V. It features high precision, low line and load regulation (0.1%), thermal shutdown, current limiting, and safe operating area control. Designed in TO-220, DPAK, and TO-220FP packages, it’s easy to regulate voltage by adjusting the external resistive divider. Its floating operation allows high-voltage regulation, ideal for power supply projects requiring adjustable output and reliable performance.
