he PJ431, A, B integrated circuits are three-terminal
programmable shunt regulator diodes. These monolithic IC
voltage references operate as a low temperature coefficient
zener which is programmable from Vref to 36 volts with two
external resistors. These devices exhibit a wide operating
current range of 1.0 to 100mA with a typical dynamic
impedance of 0.22
. The characteristics of these references
make them excellent replacements for zener diodes in many
applications such as digital voltmeters, power supplies , and
op amp circuitry. The 2.495 volt reference makes it
convenient to obtain a stable reference from 5.0 volt logic
supplies, and since The PJ431, A, B operates as a shunt
regulator, it can be used as either a positive or negative tage
reference.

SOP-8 is an internally modified SOP-8 Package. Pins 2,3,6 and 7
are electrically common to the die attach flag. This internal lead
frame modification decreases package thermal resistance and
increases power dissipation capability when appropriately
mounted on a printed on a printed circuit board. SOP-8 conforms
to all external dimensions of the standard SOP-8 Package
.
