SE431 Adjustable precision shunt regulator, 2.495V to 36V, SOT-23-3(L), SOT-23-5L, SOP-8, TO-92 and SOT-89

The SE431 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 2.5 V) to 36V with two external resistors. This device has a typical output impedance of 0.08Ω. Active output circuitry provides a very sharp turn on characteristic, making this device excellent replacement for Zener diodes in many applications. The SE431 is characterized for operation from -40°C to 125°C, and is available in five package options (SOT-23-3, SOT-23-5, SOP-8, TO-92 and SOT-89)

SE431 is a possible replacement for Texas Instruments TL431 device.
