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 1.5kΩ resistor into each pin.
Note 3: Operating junction temperature must be evaluated, and derated as needed, based on ambient temperature (T_A), power dissipation (P_D), maximum
allowable operating junction temperature (T_J(MAX)), and package thermal resistance (θ_JA). See Application Information.
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_IN operating voltage is the limiting factor.
Note 8: The value of θ_JA for the TO-263 (TS) package and TO-263 THIN (TJ) package can range from approximately 30 to 60°C/W depending on the amount of
PCB copper dedicated to heat transfer (See Application Information).
