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 1.24V
(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.
