Electrical Characteristics
V
*1. Temperature change ratio of the output voltage
*2. Specified output voltage
*3. Output voltage temperature coefficient
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.
