At the back of the circuit and load or regulating circuit, turn out large variation of double power supply voltage appears, lane for a long time didn't results, strives for the big help, thank you!!!!!

Set has a problem, should be on op-amp U1 1 foot,

This is for shrimp? Double power source is such a lane?

Yes, seems to have this problem, but found that can be a problem after I added a load

Will is behind a load, will affect the partial pressure in front of, you can see, I posted on the 4th floor

This is normal, in order to reach the op-amp output near the ground potential, because of your output load imbalance, op-amp output should be adjusted to meet the requirements of your output, change is very small, if you load balance your output is normal now,

Ok, I see, thank you
