The fixed typical application circuit of 3-terminal IC is shown in the figure. In the figure, C1 and C2 are used for frequency compensation to avoid self-oscillation and high-frequency noise; C3 is a polymer capacitor, and it can weaken the effect, which is from the low-frequency imported by the power supply, on the output voltage; D is a protection diode, when the input terminal is short, it can offer C3 a discharging circuit to stop the voltage on C3 breaking down the emitter of the regulating device. The requirement of the 3-terminal regulated IC circuit is:
