VER.A
he PJ1431 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
Programmable Output Voltage to 36 Volts
Low Dynamic Output Impedance, 0.22 Type
Sink Current Capability of 1.0 to 100 mA
Equivalent Full-Range Temperature
Coefficient of 50 ppm/ ℃Typical

Low Output Noise Voltage
them excellent replacements for zener diodes in many
applications such as digital voltmeters, power supplies ,
and op amp circuitry. The 2.5 volt reference makes it
convenient to obtain a stable reference from 5.0 volt
logic supplies, and since The PJ1431 operates as a shunt
regulator, it can be used as either a positive or negative
tage reference.
