SE432L Datasheet, PDF (1/7 Pages) Seaward Electronics Inc. – Adjustable Precision Shunt Regulator

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^oC to 105^oC, and two package options (SOT-23
and TO-92) allow the designer the opportunity to
select the proper package for their applications.
