Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the component 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 2: All voltages are with respect to the potential at the GND pins.
Note 3: Battery/Charger voltage should be above 6V no more than 10% of the operational lifetime.
Note 4: Voltage tolerance of LP55281 above 6.0V relies on fact that V

Note 5: Internal thermal shutdown circuitry protects the device from permanent damage. Thermal shutdown engages at T
= 140°C (typ.)
Note 6: For detailed soldering specifications and information, please refer to National Semiconductor Application Note AN1112 : Micro SMD Wafer Level Chip
Scale Package or National Semiconductor Application Note AN1412 : Micro SMDxt Wafer Level Chip Scale Package.
Note 7: The Human Body Model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. MIL-STD-883 3015.7
Note 8: In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature may have to be
derated. Maximum ambient temperature (T

Note 9: Junction-to-Ambient thermal resistance is highly application and board-layout dependent. In applications where high maximum power dissipation exists,
special care must be paid to thermal dissipation issues in board design.
Note 10: Min and Max limits are guaranteed by design, test or statistical analysis. Typical numbers are not guaranteed, but do represent the most likely norm.
Note 11: Low-ESR Surface-Mount Ceramic Capacitors (MLCCs) used in setting electrical characteristics.
