Compensate current drawn by LM7805 on GND/+12V only

Description
Add a resistor between -12V/GND to compensate current drawn by LM7805 on GND/+12V
Need to evaluate the current drawn by LM7805 to power all the digital circuitry
- Description updated (diff)
Only able to compensate 20mA and use a 1/4W Resistor between GND and -12V.
If Q4 is still too warm, more similar R can be added to waste some more mA here
- Status changed from Nouveau to Résolu
- % Done changed from 0 to 100
Applied in changeset fc005-electronicload|commit:73cabebd45df.
