General Description
The EC432 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 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 EC432 is characterized for operation from 0oC to 105oC, and four package options (SOT23-3L, SOT23-5L, TO92-3L and SOP8) allow the designer the opportunity to select the proper package for their applications.
