OPERATION
In these ICs, fluctuation in Output Voltage V
OUT
is detected by Feed-back Registers R1, R2, and the result 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.
