＜Recommended Components (Example)＞
These resistors determine the output voltage:
C3 is for compensating the stability of application frequency characteristics.
When C3 is not available, overshoot or undershoot is possible in starting or in rapid change of load.
Be sure to insert 0.47 μF.
Select resistors less than 10kΩ.
