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 does not guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics.

Note 2: The human body model is a 100pF capacitor discharged through a 1.5k

Ω resistor into each pin.

Note 3: Operating junction temperature must be evaluated, and derated as needed, based on ambient temperature (T

allowable operating junction temperature (T

Note 4: Output voltage line regulation is defined as the change in output voltage from the nominal value due to change in the voltage at the input.

Note 5: Output voltage load regulation is defined as the change in output voltage from the nominal value due to change in the load current at the output.

Note 6: The line and load regulation specification contains only the typical number. However, the limits for line and load regulation are included in the output

voltage tolerance specification.

Note 7: Dropout voltage is defined as the minimum input to output differential voltage at which the output drops 2% below the nominal value. For any output

voltage less than 2.5V, the minimum V
