5-CH MOTOR DRIVE IC
APPLICATION SUMMARY (Continued)
- Regulator part
Fig. 4. Regulator
As we can see in Fig. 4, the power transistor of the regulator is internally provided in IP4001S, thus the
external power transistor is not needed. Since the regulator output (typical 5V) is provided by the npn
transistor, the relatively small capacitor (e.g. 103) is sufficient for eliminating the output ripple or noise voltages.
