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 recommended.
