Typical Thermal Characteristics
Output Voltage (Rated) vs. Temperature
Figure 15 shows the regulator steady state performance
when fully loaded (500mA) from –25°C up to the rated
maximum temperature of 70°C. The output variation at
maximum load is approximately 20mV across the shown
operating temperature. This translates to a temperature
coefficient of approximately ±30ppm/°C.
POR
Figure 16 shows the
from –25°C up to the maximum rated junction tempera-
ture. The overall 150°C change in junction temperature
causes less than a 5mV variation in the
voltage. This translates to a temperature coefficient of
±6ppm/°C.
The POR pulse duration does not vary with temperature.
V
Figure 17 shows the V
temperature from –25°C to the maximum rated junction
temperature with no load on the device. The supply
current changes less than 1µA over the entire 150°C
range shown in the plot.
