Fig 3.2. Output Voltage (Rated) vs. Temperature. 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.

Ambient Temperature [° C]

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.
