General Description

The

CP432/432A are 3-terminal adjustable

precision shunt regulators with guaranteed stable

temperature

over

the

applicable

extended

commercial temperature range. The output voltage

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

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.
