5. 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
).

6. Dropout voltage is the minimum voltage difference between the input and the output at which the output voltage drops 2% below its nominal value.
For any output voltage less than 2.5V, the minimum V
IN
operating voltage is the limiting factor.
7. The line and load regulation specification contains only the typical number. However, the limits for line and load regulation are included in the adjust
