Description Features The SE431D is a low voltage three terminal  Low voltage operation (2.5V) adjustable shunt regulator with a guaranteed  Wide operating current range 150µA to 150 mA thermal temperature  Low dynamic output impedance 0.08(Typ.). ranges. The output voltage can be set to any value  Trimmed bandgap design up to + 0.5%. between VREF (approximately 2.5 V) to 36V with two  Electrostatic discharge voltage 2.5kV. external resistors. This device has a typical output  RoHS Compliant and 100% Lead (Pb)-Free. stability over impedance of 0.08Ω. applicable Active output circuitry provides a very sharp turn on characteristic, making this device excellent replacement for Zener diodes in many applications. The SE431D is characterized for operation o o from -40 C to 125 C, and five package options (SOT-23-3, SOT-23-5, SOP-8, TO-92 and SOT-89) allow the designer the opportunity to select the proper package for their applications.
