Figure 2. Operation

Fluctuation of each regulator’s output voltage, or

VOUT1, 2, 3 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 standby mode is available by a chip enable

circuit.
