■APPLICATION SUMMARY(Continued)

- Tray motor speed control

The amplitude of the output voltage is controlled by pin20(CTL).

S30011

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

S30011 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),
