Fluctuation of each regulator’s output voltage, or VOUT1, VOUT2, VOUT3 is detected individually. Then it is put back
to an error amplifier through feedback resistors, or R1_1, R2_1, R1_2, R2_2, R1_3, R2_3 and compared with a
reference voltage and compensated for the result and make a constant voltage.
In each regulator, short protection is made with a current limit circuit and stand-by mode is available by a chip
enable circuit.
