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 V
REF
(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擄C to 105擄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.
Pb-free, RoHS compliant.
