Notes
10.
Not tested. Guaranteed by design.
11.
These threshold parameters are specified as a ratio of VTEMP/VREF. Due to the negative-temperature-coefficient thermistor, VTEMP
rises when the temperature is falling from high to low, and VTEMP falls when the temperature is rising from low to high.
Table 4. Static Electrical Characteristics (continued)
Characteristics noted under conditions VIN = 5.0V, -40°C ≤ TA ≤ 85°C, CIN = COUT = 1µF (see Figure 1), unless otherwise
noted. Typical values noted reflect the approximate parameter means at VIN = 5.0V and TA = 25°C under nominal conditions,
unless otherwise noted.
