AP432
General Description
The
AP432
are 3-terminal adjustable precision
shunt
regulators with guaranteed stable
temperature over
the applicable extended
commercial temperature
range. The output voltage
may be set at any level
greater than 1.24\/ (V
REF
) up
to 20V merely by
selecting
two external resistors
that act as a voltage
divider network. These devices
have a typical output
impedance of 0.2Ω. Active
output circuitry provides
very sharp turn-on
characteristics, making these
devices excellent
improved replacements for Zener
diodes
in many
applications.
The precise +/- 1% reference voltage tolerance of
the
AP432
make it possible in many
applications to avoid
the use of a variable resistor,
consequently saving cost
and eliminating drift and
reliability problems associated
with it.
