DESCRI PTI O N
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 chose 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, 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)
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 micro power applications.
