In my circuit including a LM317T configured as a current regulator, the input and output voltages to the IC are respectively 43V and 40V. Is that high of voltages permissible? In the data sheets for example from ON Semiconductor, it is stated that the input-output voltage differential must not exceed 40V, but that both voltages can be any number above ground. Is that actually the case would you say with this regulator?
Also, output current is 0.5A. Would 40V times 0.5A equals 20W be more output power than this regulator can accommodate?
My problem is with overheating of LM317T even with a substantial heat sink attached to the regulator. This might be related to the entire circuit including the regulator, but I'll leave showing the entire circuit to a later date, perhaps.
Thanks in advance for your feedback,
Pete
