Capacitor C3
This capacitor is utilized to stabilize the frequency characteristics, but is seldom used. However, if the phase margin is
insufficient and oscillation is likely, connecting this capacitor may improve frequency stability.
Resistor R1,R2
These resistors determine the output voltage:
VOUT＝1.0V×(1 + R1/R2)
Select resistors less than 10kΩ.
