*4. The dropout voltage is limited by the difference between the input voltage (min. value) and the set output voltage.

In case of 1.0 V

In case of 1.5 V

*5. Due to limitation of the power dissipation, this value may not be satisfied. Attention should be paid to the power

dissipation when the output current is large.

This specification is guaranteed by design.
