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 5[V], the regulator output voltage (pin 46) because 5[V]. If the voltage
eliminator and should have good temperature characteristics.
Vout = 2
of pin 43 is 0[V], the output voltage of pin 46 because 0[V].
2.5 = 5[V] (where R1 = R2)
