Description
The AP431/AP431A are 3-terminal adjustable
precision
shunt
regulators
temperature stability over the applicable extended
commercial temperature range. The output voltage
may be set at any level greater than 2.495V(V
REF
)
up to 36V merely by selecting two external resistors
that act as a voltage divider network. These devices
have a typical output impedance of 0.2
. 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 AP431/431A 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.
