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: VIN = VEN = (VOUT + 1.5V), IOUT = 10 mA, Tj = 25C. All values in bold are over the full temperature
range.
