may be set at any level greater than 1.24\/ (V
to 20V merely by selecting two external resistors
that act as a voltage divider network. These devices

improved replacements for Zener diodes in many
applications.
The precise +/- 1% reference voltage tolerance of
the CP432/432A 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.
