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.

Voltage Threshold Temperature Variation

from –25°C up to the maximum rated junction tempera-

ture. The overall 150°C change in junction temperature

voltage. This translates to a temperature coefficient of

±6ppm/°C.

The POR pulse duration does not vary with temperature.

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.
