In these ICs, fluctuation of Output Voltage, V
OUT
is detected by Feed-back Registers, R1 and R2, and the result is compared
with a reference voltage by 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.
