4. Regulator & Reset Function
The regulator and reset circuits are as illustrated in Figure 1.
where R1=R2.
• The external circuit is composed of the transistor, KSB772 and a capacitor, about 33[ F]. The capacitor is used as a ripple
• The regulator output voltage (pin 46) is decided as follows.
• When the voltage of pin 43 (Vreset) is at 3.3[V], the regulator output voltage (pin 46) because 3.3[V]. If the voltage
