Product parametric performance is indicated in the Electrical Characteristics for the listed test conditions, unless otherwise noted. Product
performance may not be indicated by the Electrical Characteristics if operated under different conditions.
7. Only for 5 V Version. Measured when the output voltage V
Q
has dropped 100 mV from the nominal value obtained at V
I
= 13.5 V.
8. Guaranteed by design, not tested in production.
