Description
The SE432L is a low voltage three terminal
adjustable shunt regulator with a guaranteed
thermal
stability
over
applicable
temperature
ranges. The output voltage can be set to any value
between V
REF
(approximately 1.24 V) to 8V with two
external resistors. This device has a typical output
impedance
of
0.30Ω.
Active
output
circuitry
provides a very sharp turn on characteristic, making
this device excellent replacement for Zener diodes
in many applications.
The SE432 is characterized for operation from
-40
o
C to 105
o
C, and two package options (SOT-23
and TO-92) allow the designer the opportunity to
select the proper package for their applications.
