Electrical Characteristics
Note 2: All voltages are with respect to the potential at the ground pin.
Note 3: Maximum Power dissipation for the device is calculated using the following equations:
where T
package θ
thus below 25˚C the power dissipation figure can be increased by 4.5mW per degree, and similarity decreased by this factor for temperatures above 25˚C. The value
of the θ
resistance and power dissipation for the LLP package, refer to Application Note AN-1187.
Note 4: Typical Values represent the most likely parametric norm.
Note 5: All limits are guaranteed by testing or statistical analysis.
Note 6: Human body model: 1.5kΩ in series with 100pF.
Note 7: Condition does not apply to input voltages below 2.5V since this is the minimum input operating voltage.
Note 8: Dropout voltage is measured by reducing V
version.
Note 9: The SET pin is not externally connected for the fixed versions.
Note 10: The FAULT detection voltage is specified for the input to output voltage differential at which the FAULT pin goes active low.
