GS317 Datasheet | Globaltech

3-Terminal Adjustable Regulator Product Description The GS317 are adjust able 3-terminal p ositive voltage regu lators is cap able of suppl ying in excess of 1.5A over a 3V t o 40V out put range. They ar e e xceptionally e asy to use and re quire only t wo e xternal resistors to set the output voltage. F urther, both line an d loa d regu lation i s better than standard fixed regulators. In additi on to high er perfo rmance tha n fixed regulators, the GS317 ser ies of fers full overload protection avai lable onl y in IC’ s. Includ ed on th e chip are current limit, therma l overload protection and safe area protection. All overl oad protectio n circ uitry rem ains full y functional eve n if the adju stment terminal i s disconnected. Normally, no capacitors are needed unless the d evice is situ ated far from the inp ut filter cap acitor in which cas e an input by pass is needed. An option al o utput cap acitor ca n b e added to improve transient response. The primar y appl ications of each of these regulators is that of a pr ogrammable output regulator, but b y conn ecting a fixe d resistor between the adjustment terminal and the o utput terminal, each devic e can be used as a precision current regulator. Even thou gh the reg ulator is “floating” an d sees only i nput-to-output dif ferential volt age, us e of these dev ices to regulat e output volt age that would caus e the max imum-rated dif ferential voltage to be exce eded if the output be came shorted to ground is not remended.
