Thermal Parameters
Note 1: 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 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 (SS) is ±1.5 kV.
Note 3: Device power dissipation must be de-rated based on device power dissipation (P
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.
