In these ICs, fluctuation of output voltage, VOUT is detected by feed-back registers R1, R2, and the result is
compared with a reference voltage by the error amplifier, so that a constant voltage is output. A current limit
circuit for protection at short mode and a chip enable circuit, are included.
