DESCRIPTION
The UC39431 is an adjustable shunt voltage regulator with 100mA sink ca-
pability.
The
architecture,
comprised
transconductance amplifier, gives the user separate control of the small
signal error voltage frequency response along with a fixed linear
transconductance. A minimum 3MHz gain bandwidth product for both the
error and transconductance amplifiers assures fast response. In addition to
external programming, the IC has three internal resistors that can be con-
nected in six different configurations to provide regulated voltages of 2.82V,
3.12V, 5.1V, 7.8V, 10.42V, and 12.24V. A sister device (UC39432) provides
access to the non-inverting error ampilifer input and reference, while elimi-
nating the three internal resistors.
