*1. Change in temperature of the output voltage
*2. Set output voltage
*3. Output voltage temperature coefficient
*5. The output current can be at least this value.
Due to restrictions on the package power dissipation, this value may not be satisfied. Attention should be paid to the power
dissipation of the package when the output current is large.
This specification is guaranteed by design.
