The gain frequency characteristics can be lowered by
connecting a capacitor between this pin and ground to
prevent oscillation.

Speed control
The LB1854M implements a voltage control scheme in
which the output voltage is controlled by the pin 5 voltage.
The pin 4 voltage determines the control start voltage.
