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 100mΩ. The reduced reference input bias current and minimum operating currents make these devices suitable for portable and micro power applications.
