SE432

SEAWARD ELECTRONICS INC. Adjustable Precision Shunt Regulator Features ¾ ¾ ¾ ¾ ¾ ¾ Low voltage operation (1.24V) SE432 Description The SE432 is a low voltage three terminal adjustable shunt regulator with a guaranteed www.datasheet4u.com thermal stability 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) 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 their applications.
