6. Temperature coefficient of output voltage
SUPER-SMALL PACKAGE 2-CIRCUIT HIGH RIPPLE-REJECTION LOW CURRENT CONSUMPTION LOW DROPOUT CMOS VOLTAGE REGULATOR
The shaded area in Figure 22 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. Change in temperature of output voltage
*2. Specified output voltage
