Electrical Specifications
Electrical characteristics are guaranteed over the full temperature range -40ºC <Tj< 125ºC. Ambient
temperature must be de-rated based upon power dissipation and package thermal characteristics. Unless
otherwise specified: VENABLE = VIN = (VOUT + 1.5V), IOUT = 10 mA, Tj = 25C. Values in bold are over the full
temperature range.
