摘要：
A power supply control device includes a switching regulator, a linear regulator, a switching unit, a consumed current detection unit, a current determination unit, and a power determination unit. The consumed current detection unit detects a consumed current of the regulator serving as a power supply to the load. The current determination unit determines whether or not the consumed current is greater than or equal to a predetermined current. The power determination unit determines whether or not a consumed power of the regulator is greater than or equal to a predetermined power. The switching unit connects the linear regulator to the load when the consumed current is lower than the predetermined current and the consumed power is lower than the predetermined power.
