Three-terminal voltage stabilizing integrated circuit working performance test circuit

The working performance test circuit of the three-terminal voltage stabilizing integrated circuit is shown in the figure. Apply DC voltage to the ① and ② pins of the three-terminal voltage regulator (in the picture, an adjustable DC power supply G is used). When adding, be sure to pay attention to the polarity of G. Ui should be greater than the voltage stabilization value U of the voltage regulator. It should be at least 2V higher, but no higher than 35V. Set the multimeter to the DC voltage range and measure the voltage between pins ③ and ② of the voltage regulator, which is the stable voltage of the voltage regulator.
