Electrical Specifications
Electrical characteristics are guaranteed over the full temperature range –40ºC <Tj<105ºC. Ambient
temperature must be de-rated based upon power dissipation and package thermal characteristics. Unless
otherwise stated, test conditions are VCC = 3V, VCOMP = VFB, ICOMP = 1mA
