regulators with a guaranteed thermal stability over the applicable
temperature range. The output voltage can be set to any value
between V
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 SS2432G is characterized for operation from 0°C to 105°C.
