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[µF]. The capacitor is used as a ripple

eliminator and should have good temperature characteristics.

• The regulator output voltage (pin 41) is decided as follows.

Vout = 2 × 2.5 = 5[V] (where R1=R2)

• When the voltage of pin 44 (Vreset) is at 5[V], regulator output voltage(pin 41) is 5[V], and if 0[V], the output voltage

of pin 41 is 0[V].
