PJ432/PJ432A/PJ432B
Adjustable Precision Shunt
The PJ432 is a three-terminal adjustable shunt regulator
with specified thermal stability. The output voltage may
be set to any value between Vref (approximately 1.24V) and
18V with two external resistors. The PJ432 has a typical
output impedance of 0.15 Ω . Active output circuitry
provides a very sharp turn-on characteristic, making the
PJ432 excellent replacement for zener diode in many
applications.
