DESCRIPTION
The SS432G is a low-voltage three-terminal adjustable shunt
regulator with a guaranteed thermal stability over the applicable
temperature range. The output voltage can be set to any value
between VREF (approximately 1.24V) to 12V with two external
resistors (see application circuit). This device has a typical output
impedance of 0.25 ohms. Active output circuitry provides very sharp
turn-on characteristics, making this device an excellent
replacement for Zener diodes in many applications.
The SS432G is characterized for operation from 0°C to 105°C,
and three package options (SOT-23, SOT-89, and TO-92) allow
the designer the opportunity to select the proper package for his
application.
