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.
