Tray motor speed control
The amplitude of the output voltage is controlled by pin20(CTL).

ZD
Normally, the differential output voltage is 3.1V when the pin20(CTL) is open.
If you want to control differential output voltage of the tray drive part, insert external resistor R and zener
diode ZD as shown in figure 6.
Zener diode ZD is only needed when you want to obtain a precision output voltage,
In other case you only insert an external resistor R.

Regulator part
IP4001 has a temperature independent voltage source internally.
So in the figure 7, the reference voltage (2.5V) is generated by the internal circuit (bandgab reference).

Because the power NPN TR Q5 is inserted
internally, there is no need to attach
an external active component.
