Hello all,
I've found a nice circuit around, for an LM350T variable power supply, and I built it.
Here the link:
https://www.eleccircuit.com/lm350-adjustable-voltage-regulator/
I added a second pot, as indicated in the linked page, for a precision settings, and thus the circuit become this one:
Everything was perfectly working ( voltage regulation and so on ) so basically I havn't made any (big ) mistake.
( In effect I did inverted values for C3 and C4 but it was working fine )
Reading trough the datasheet I've seen that the IC has short circuit protection so I tried to short the output ( I'm a bit disorded on my bench and sometimes it happen to me to have too much stuff on it and the output get shorted
) and immediatelly the LM350 blown.
Alle the diode were in correct position as per circuit and datasheet
Can someone help me in understanding why it blown ?
Thanks in advance
Pierluigi
