GS-R218

GS-R218 27W SWITCHING REGULATOR FOR AUTOMOTIVE APPLICATION Type GS-R218 Vi 10,5 to 16,0 V Vo 18 V Io 1,5 A DESCRIPTION The GS-R218 is a switching voltage regulator that can deliver an output current of 1,5 A at 18 V when supplied by a car battery. The regulator uses a cigar lighter case with a coiled cord and it is protected against overloads and short circuits at the output (latching overload protection: to restart the regulator after the intervention of the overload protection, the input voltage must be switched OFF and ON again).
