6) When the input voltage through the pin # 3 is below the VREF, then the direction of the motor in forward
direction.
7) When the input voltage through the pin # 3 is above the VREF, then the direction of the motor in reverse
direction.
8) If it is desired to change the gain, then the pin # 4 or # 24 can be used.
5. RADIATION FIN IS CONNECTING TO THE INTERNAL GND OF THE PACKAGE.
Connect the fin to the external GND.
6. REGULATOR
This is a typical series regulator that generates a reference voltage internally. A PNP low saturation type tran-
sistor must be connected.
