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
