Low voltage operation (1.24V)
adjustable shunt regulator with a guaranteed
thermal stability over applicable temperature
ranges. The output voltage can be set to any value
between VREF (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.
Adjustable output voltage V0 =VREF to 8V
Wide operating current range 60µA to 100mA
Low dynamic output impedance 0.30Ω (Typ.)
Trimmed bandgap design up to + 0.5%.
ESD rating is 2.5KV(Per MIL-STD-883D)
Available in Lead-Free Packages.

The CYT432 is characterized for operation from
0oC to 105oC, and four package options (SOT-23
and TO-92) allow the designer the opportunity to
select the proper package for their applications.
