Note 1: Absolute Maximum Ratings are limits beyond which damage can 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 pin.

Note 3: For further information on these packages please refer to the following application notes;AN-1112 Micro SMD Package Wafer Level Chip Scale

Package,AN-1187 Leadless Leadframe Package.

Note 4: Internal thermal shutdown circuitry protects the device from permanent damage.

Note 5: The human body model is 100pF discharged through a 1.5k

Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly into each

pin.

Note 7: Dropout voltage is voltage difference between input and output at which the output voltage drops to 100mV below its nominal value. This parameter only

for output voltages above 2.0V.

Note 8: Junction to ambient thermal resistance is dependant on the application and board layout. In applications where high maximum power dissipation is possible,

special care must be paid to thermal dissipation issues in board design.

Note 9: The device maintains the regulated output voltage without the load.

Note 10: This electrical specification is guaranteed by design.

Note 12: Enable Pin has 1M

Ω typical, resistor connected to GND.

Statistical Quality Control methods. Operation over the temperature specification is guaranteed by correlating the electrical characteristics to process and

temperature variations and applying statistical process control.
