Electrical Characteristics
Unless otherwise noted, V
and limits appearing in normal type apply for T
range for operation, −40 to +125˚C. (Notes 14, 15)
Note 3: Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device
is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical
Characteristics tables.
Note 4: All voltages are with respect to the potential at the GND pin.
Note 5: For information regarding micro SMD and LLP packages please refer to the following application notes;
AN-1112 Micro SMD Package Wafer Level Chip Scale Package,
AN-1187. Leadless Leadframe Package.
Note 6: Internal Thermal shutdown circuitry protects the device from permanent damage.
Note 7: In applications where high power dissipation and/or poor thermal resistance is present, the maximum ambient temperature may have to be derated.
Maximum ambient temperature (T
the junction to ambient thermal resistance in the application (θ
Note 8: Junction to ambient thermal resistance is highly dependant on the application and board layout. In applications where high thermal dissipation is possible,
special care must be paid to thermal issues in the board design.
Note 9: The human body model is an 100 pF discharge through a 1.5 kΩ resistor into each pin. The machine model is a 200 pF capacitor discharged directly into
each pin.
Note 10: The device maintains a stable, regulated output voltage without load.
Note 11: This electrical specification is guaranteed by design.
