Voltage stabilizer circuit outputs the positive and negative voltage simultaneously

Some circuits need the voltage source that can output the positive and negative voltage simultaneously, we can form the voltage stabilizer circuit that outputs the positive and negative voltage simultaneously by using the CW7800 series and CW7900 series integrated voltage stabilizers. The circuit is as shown in the figure. Voltage stabilizer circuit outputs the positive and negative voltage simultaneously Because this circuits use the same group of rectifier circuit, so the circuit is simple. But it is not suitable for the two-way unbalanced load circuit, otherwise it will result in the increasing of the output voltage error to destroy the stability.
