Description
The GTL432 series are three-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 0.2
. Active output circuitry provides very sharp turn-on characteristics, making these devices
excellent improved replacements for Zener diodes in many applications.
The precise +/- 2% reference voltage tolerance of GTL432 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.
