voltage.
The change in temperature [mV/°C] is calculated using the following equation.
*1. Change in temperature of the output voltage
*2. Specified output voltage
*3. Output voltage temperature coefficient
The output current can be at least this value.
Due to limitation of 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.
