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. WebThe linear voltage regulator opens the output transistor so that the voltage between the output and the feedback pin is 5 volts if it is a 7805, or 1.25 V in the case of an LM317. All excess voltage falls on the line stabilizer transistor. This transistor is connected in series with the power consumer. Therefore the current through them is the ...
