7. Temperature Coefficient of Output Voltage
ULTRA LOW CURRENT CONSUMPTION AND LOW DROPOUT CMOS VOLTAGE REGULATOR
The shadowed area in Figure 10 is the range where V
temperature coefficient of the output voltage is ±120 ppm/°C.
A change in the temperature of the output voltage [mV/°C] is calculated using the following equation.
*1. The temperature change ratio of the output voltage
*2. Specified output voltage
*3. Output voltage temperature coefficient
