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: V

ENABLE

= V

IN

= (V

OUT

+ 1.5V), I

OUT

= 10 mA, Tj = 25C. All values in
