How does a lm317 voltage regulator work

WebThe LM317 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 typical load regulation of 0.1%. WebApr 21, 2016 · gargrahul277. I'm using LM317T (TO-220) to generate 14V DC from a 24 V DC SMPS. my load current is 300mA. At start the regulator ic gives 14V at its output precisely. But the output started dropping as the ic started heating. within 5 minutes the output dropped from 14V to 13.7V and the ic got very hot. I applied heat sink to it.
