In these ICs, Output Voltage V

OUT

is detected by Feed-back Registers R1, R2, and the detected Output Voltage is

compared 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 for standby function are included.
