LP8340I Electrical Characteristics
Unless otherwise specified all limits guaranteed for V
the full operating temperature range of T
Note 1: Absolute Maximum ratings indicate limits beyond which damage may occur. Electrical specifications do not apply when operating the device outside of its
rated operating conditions.
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
the LLP package is specifically dependant on the PCB trace area, trace material, and the number of layers and thermal vias. For improved thermal 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 2.7V since this is the minimum input operating voltage.
Note 8: Dropout voltage is measured by reducing V
