OPERATION
In these ICs, Output Voltage VOUT is detected by Feed-back Registers R1, R2, and the detected Output Voltage is compare
with a reference voltage by Error Amplifier, so that a constant voltage is output.
A current limit circuit working for Short Protect and a chip enable circuit are included.
