„ Ordering Information
„ General Description
The AP432/432A 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 AP432/432A 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.
