LDO Regulator Application Note

Dual LDO Regulator

There are single input type and dual input type in dual LDO regulators.
The single input type has one shared input pin for both regulators, it becomes a small package because it can reduce the number of pins. However, it the difference between the input voltage and the output voltage is large, since the input voltage of both regulators is same voltage, the energy loss and the power dissipation becomes large.
