Hello.
I would like to know the maximum Tj value of L78.
I think the junction temperature of silicon semiconductors is generally 150°C, but the data sheet states that the operating junction temperature range is 0 to 125°C for L78 and 0 to 150°C for L79.
The solid line in Figure 31 of the data sheet seems to go up to 150°C,
but is the starting point for thermal design 125°C?
Thank you in advance.
