My mistake must be simple, but I can’t spot it. Screen capture is attached. Try putting a load resistor from each output to ground.

Depending on the construction of the model for the regulator, it is possible that it needs a minimum load. Thanks Lynn I tried that with a 1k load and that resulted in an output voltage of I swapped the LM for another -5V regulator, the UPC, which gave the correct output but failed after a few seconds.
The convergence assistant suggest to switch the integration to the Gear algorithm, which resulted in a stable and correct output. So Datashert cannot simulate the output of a garden variety, ultra common, component like the LM Perhaps changes to other options in the “Custom Analysis Options” dialog will improve the convergence.
If anyone datasheet suggestions I would be most gratefull. The output regulation is specified for a current change from 5 mA to 1 A.
The maximum value is mV. Although the datasheet does not specify or call for any minimum load, it also does not specify the performance at no load. Most Active Software Boards: Auto-suggest helps you quickly narrow down your search results by suggesting possible matches as you type.

Message 2 of 5. So I went back to the LM but that still resulted in the incorrect output.
