Electrical Specifications
Electrical characteristics are guaranteed by design over the full temperature range –40ºC <Tj<135ºC. Ambient
temperature must be de-rated based upon power dissipation and package thermal characteristics.
Unless otherwise stated, test conditions are Vin=Vout+0.5V, Iout=1mA, Tj=+25ºC.
