ET432
Adjustable Precision Shunt Regulator
Description
The ET432 is a three-terminal
adjustable shunt regulator series with
a guaranteed thermal stability over
applicable industrial temperature
ranges and wide operating current(up
to 100mA).The output voltage
between 1.24 and 18 volts by selection
of two external divider resistors.
The ET432 have a typical output
impedance of 0.2 Ω . Active output
circuitry provides a very sharp turn-on
characteristic, making the APL431L
excellent replacements for zener
diodes in many applications, including
on-board regulation and adjustable
power supplies.
