The input voltage of the emitter output circuit is fixed at VZ, so the output voltage VO=VZ-VBE is also fixed. When the grid voltage is fluctuating, as VZ is almost still and VO is the same, the change of VI is adjusted by VCE, so the triode is called the adjusting pipe. When RL changes and it causes the fluctuation of IO, as lone as the △IZ is in the normal range of the stabilovolt tube, VZ will remains the same, i.e VO is almost stable.
The fluctuation of the circuit output current can be expanded to (1+β)△IZ, so it is also called the enlarging voltage stable diode circuit. (View)

The 3-terminal adjustable regulated power supply circuit adjusts the output voltage by external resistors, to be sure the precision and stability of the output voltage, we should choose the precise resistor, and the resistor must be close to the regulator, prevent the output current from generating faulted voltage on the lines. In the figure is the application circuit of a 3-terminal dual adjustable regulated power supply, whose output voltage is:
In the figure is the 3-terminal dual adjustable regulated power supply circuit composed of LMLMl17and LM137. The figured VREF is equal to V31. (View)
