terminal shunt voltage regulators are pin-to-pin

compatible with the industry standard TL431, but

with significant improvements.

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.

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
