Can the TL783 be used to regulate negative voltage by connecting the output to my system ground and using the regulator ground as my negative voltage source? I couldn't find anything in the datasheet pertaining to negative regulation except something like this:
The device works to keep the voltage at the OUT pin 1.25 V higher than the voltage at the ADJ pin. Therefore, a resistor divider can be used to set the output voltage.
This would lead me to believe it should work as I described, but I'd like to verify with someone who knows more than me about this.
