So I made the RB regulator in LTspice today, but it doesn't oscillate for some reason. ![Frown :( :(](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I made sure it was exactly like the diagram, with the right values, etc..., but it doesn't oscillate.
The zener voltage is 6.28
The power supply(Vi) voltage is 20
The output voltage(Vo) is 5.99
The current draw from the power supply is 2.9
And making a 100 ohm load doesn't do anything except drop Vo to about 2v
Any ideas?
