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