reducing the current drain from batteries
in portable equipment as well as reducing
the voltage programming errors due to
the impedance of the divider network
(See Product Highlight figure below). In
addition, the LX6431B has an improved
initial accuracy of 0.4%, and the output
voltage is programmable by using two
external resistors from 2.5V to 36V.
These devices offer low output
impedance for improved load regulation.
The typical output impedance of these
devices is 100m
. The reduced
reference input bias current and minimum
operating currents make these devices
suitable for portable and micropower
applications.
The LX6431 series precision adjustable
three terminal shunt voltage regulators are
pin-to-pin compatible with the industry
standard TL431, but with significant
improvements. The LX6431 design has
eliminated regions of instability common
to older generation shunt regulator
products like the TL431. Designs are
made simpler by eliminating the task of
insuring capacitive loads, and output
voltage and cathode currents don't
combine for unstable operation. The
capacitor value is chosen simply to give
the best load transient response without
the possibility of instability. A lower
reference input current allows the use of
higher value reference divider resistors,
