EC432L-Adjustable Precision Shunt Regulator

General description

The EC432L is a low voltage three terminal adjustable shunt regulator with a guaranteed thermalstabilityoverapplicabletemperature 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 impedanceof0.30Ω.Activeoutputcircuitry provides a very sharp turn on characteristic, making this device excellent replacement for Zener diodes in many applications.

The EC432L is characterized for operation from -40℃ to 105℃, and two package options (SOT-23、SC59 and TO-92) allow the designer the opportunity to select the proper package for their applications.
