Thermal Parameters
Note 1: Absolute maximum ratings indicate limits beyond which damage to the component may occur. Operating ratings indicate conditions for which the device
is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications, see Electrical Characteristics. Specifications do not
apply when operating the device outside of its rated operating conditions.
Note 2: The Human Body Model (HBM) is a 100 pF capacitor discharged through a 1.5k resistor into each pin. Test method is per JESD22-A114. The HBM rating
for device pin 1 (EN) is ±1.5 kV.
Note 3: Device power dissipation must be de-rated based on device power dissipation (T
resistance (θ
the Application Information section for details.
Note 4: Output voltage line regulation is defined as the change in output voltage from nominal value resulting from a change in input voltage.
Note 5: Output voltage load regulation is defined as the change in output voltage from nominal value as the load current increases from no load to full load.
Note 6: Dropout voltage is defined the as input to output voltage differential (V
drop no more than 2% from the nominal value
