Electrical Specifications
Electrical characteristics are guaranteed over the full temperature range 0ºC <Tj< 125ºC. Ambient temperature
must be de-rated based upon power dissipation and package thermal characteristics. Unless otherwise
specified: V
ENABLE
= V
IN
= (V
OUT
+ 1.5V), I
OUT
= 10 mA, Tj = 25C. Values in
