4 DC and AC characteristics
This section summarizes the DC and AC characteristics of the device. The parameters in
the DC and AC characteristics table that follows are derived from tests performed under the
test conditions. Designers should check that the operating conditions in their circuit match
the operating conditions when relying on the quoted parameters.

= 25 °C, unless otherwise noted under test condition.
3. Accuracy is defined as the error between the measured and calculated output voltage at specified conditions of voltage,
current, and temperature.
4. Positive load currents flow out of the device (sourcing) and can typically be 16 µA. For negative load currents (sinking), the
device can sink less than 1 µA.
5. Over the supply range of 2.4 to 5.5 V.
6. Measured at constant junction temperature, with pulse testing and low duty cycle. Output changes due to heating may be
calculated by multiplying internal dissipation by thermal resistance.
