R1, RP1 and VD2 form a continuously adjustable constant voltage source to provide a reference voltage for the base of VT5, and R1 is a current limiting resistor.

When the VCC voltage of the power supply rises due to external reasons, the base voltage of VT4 also rises, and because the current I4 and I2 are supplied by the constant current source, I2 decreases, causing the Ube of VT1 to increase, forcing the voltage of the input power supply VCC to drop, reaching The purpose of stabilizing the voltage of the output terminal Vo; when the voltage of the power supply VCC drops, the process of stabilizing the voltage is opposite to the above process.
