Set the power supply voltage as necessary. However, always set Pin7 of CC to the maximum electric potential. Pin8 and may require a capacitor for ripple removal. As protection functions, CC reset circuit, REF detector and heat protection circuit are incorporated. The CC reset circuit operates at approx. 3 and is released at 3., when the supply (Pin7) decreases. For the REF detector, the protection function works at approx. (max. ). Also, the set temperature for operation of the heat protection circuit is approx. 80 C. PC (Power Cut) functions which can be independently controlled are incorporated in Ch. and. Supply By adding an external PNP transistor, regulator can be constructed. Attach an external capacitor for loop filter to output Pin. n Pin, the base current limiting circuit (typ. 0mA) is incorporated. CC () RL= 8Ω includes following four Product lifecycle stage. When the supply is used, the external PNP Tr emitter must be connected to pin than Pin7 (S CC pin) P Amp. When the operational amplifier is not used, make connection as follows ; REF +
