Regulate below ADJ
The feedback loop maintains OUT minus ADJ near −1.25 V.
Set the magnitude
110 Ω from OUT to ADJ and 330 Ω from ADJ to ground give a nominal output magnitude of 5 V.
Provide stable loading
The divider draws about 11.36 mA. Fit the required output capacitor, positive end toward ground, and calculate the pass-stage loss.
