The SE432 is a low voltage three terminal
adjustable shunt regulator with a guaranteed
www.datatshheeremt4aul.comstability 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.
The SE432 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
¾ Low voltage operation (1.24V)
¾ Adjustable output voltage V0 =VREF to 12V
¾ Wide operating current range 60µA to 100mA
¾ Low dynamic output impedance 0.25Ω (Typ.)
¾ Trimmed bandgap design up to + 0.5%.
¾ ESD rating is 4KV(Per MIL-STD-883D)
¾ Linear Regulators
¾ Adjustable Supplies
¾ Switching Power Supplies
¾ Battery Operated Computers
¾ Computer Disk Drives
