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

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.
