Voltage stabilizing circuit diagram with simultaneous adjustment of positive and negative voltages

In order to synchronize the positive and negative voltage regulation, there should be R1=R2 in this circuit. The actual value is 4.4~22KΩ (1~0.5%). The value of R3 is R3=0.5R2. When the potentiometer resistance value is 10~25KΩ, the current limiting resistor R4 should be 1.8KΩ. When the voltage regulation value of the integrated voltage stabilizing circuit is 5V, the output voltage of the circuit is also 5V. The maximum output voltage is equivalent to UE-2V, so it is related to the input voltage allowed by the integrated circuit.
