SE431D

The SE431D is a low voltage three terminal adjustable shunt regulator with a ranteed 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 SE431D is characterized for operation from -40o C to 125o 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. Features Ø Low voltage operation (2.5V) Ø Wide operating current range 150µA to 150 mA Ø Low dynamic output impedance 0.08(Typ.). Ø Trimmed bandgap design up to + 0.5%. Ø Electrostatic discharge voltage 2.5kV. Ø RoHS Compliant and ** Lead (Pb)-Free. Application Ø Linear Regulators Ø Adjustable Supplies Ø Switching Power Supplies Ø Battery Operated Computers Ø Instrumentation Ø Computer Disk Drive
