This shows the regulator steady state performance when fully loaded (1.5A) in an ambient temperature up to the rated maximum of 70°C. The output variation at maximum load is about 13mV across the normal temperature operating. Fig 3.3. Thresholds vs. Temperature. This shows the regulator select/deselect threshold variation up to the maximum rated junction temperature. The overall 125°C change in junction temperature causes a 30mV variation in the select threshold voltage (regulator enable). The deselect threshold level varies about 30mV over the 125°C change in junction temperature. The hysteresis remains essentially constant over the entire temperature range.
