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 12V with two external resistors.
This device has a typical output impedance of 0.25Ω.
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 12V
Wide operating current range 60µA to 100mA
Low dynamic output impedance 0.25Ω (Typ.)
Trimmed bandgap design up to + 0.5%.
ESD rating is 4KV(Per MIL-STD-883D)
Available in Lead-Free Packages.

Linear Regulators
The CYT432 is characterized for operation from 0oC
to 105oC, and four package options (SOT-23-3,
SOT-23-5, TO-92 and SOP-8) allow the designer the
opportunity to select the proper package for their
applications.
