Bonjour Roger,
Just one question ... Temp of the LP2950 case ???
see the " LP2950 Maximum Rated Output Current " current and remember the input voltage is close to the maximum of the LP ...
the current you draw is ALSO very close to the max ...
also the reason from DS DATASHEET:
''
H - High-Terminal Potentiometer. This is the high terminal of the potentiometer. It is not required that
this terminal be connected to a potential greater than the L-terminal. Voltage applied to the H-terminal
can not exceed the power-supply voltage, VCC, or go below ground.
"
It seems I already had cut and pasted this section .....
We already had this discussion too ... about frying the DS 1804 ...
Amitiés
Alain

Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

IF there is the word "Problem" in your question ...
certainly the answer is " RTFM " or " RTFDataSheet " !!!
