LM317 Regulator PIC Microcontroller low-cost digital temperature and humidityThe LM317 Regulator device is an adjustable three terminal positive voltage regulator capable of supplying more than 1. 5 A over an output voltage range of 1. 25 V to 37 V. It requires only two external resistors to set the output voltage. The device features a typical line regulation of 0. 01% and a typical load regulation of 0. 1%. It includes current limiting, thermal overload protection, and safe operating area protection. Overload protection
