Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is
intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics
Tables.
Note 2: Human body model, applicable std. MIL-STD-883, Method 3015.7. Machine model, applicable std. JESD22–A115–A (ESD MM std of JEDEC). Field-
Induced Charge-Device Model, applicable std. JESD22–C101–C. (ESD FICDM std. of JEDEC)
Note 3: The maximum power dissipation is a function of T

Note 4: Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating
of the device such that T

Note 5: Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will
also depend on the application and configuration. The typical values are not tested and are not guaranteed on shipped production material.
Note 6: Limits are 100% production tested at 25°C. Limits over temperature range are guaranteed through correlations using statistical quality control (SQC)
method.
Note 7: This parameter is guaranteed by design and/or characterization and is not tested in production.

Note 11: C
Note 12: The device maintains stable, regulated output voltage without a load.
Note 13: Appropriate output load register must be set.
Note 14: Dropout voltage is the voltage difference between the supply voltage and the output voltage at which the output voltage drops to 100 mV below its
nominal value.
