DESCRIPTIONThe UC39431isan adjustable shunt voltage regulator with 100mA sink ca-
pability. The architecture, comprised of an error amplifier and
transconductance amplifier, gives the user separate controlof the small
signal error voltage frequency response along witha fixed linear
transconductance.A minimum 3MHz gain bandwidth product for both the
error and transconductance amplifiers assures fast response.In additionto
external programming, theIC has three internal resistors that can be con-
nectedin six different configurationsto provide regulated voltagesof 2.82V,
3.12V, 5.1V, 7.8V, 10.42V, and 12.24V.A sister device (UC39432) provides
accessto the non-inverting error ampilifer input and reference, while elimi-
nating the three internal resistors.
